In addition, if the red stripe pigment attached to the above-mentioned phosphor is heated to about 450 l: it also hardly changes color, that is, regardless of its type. Specifically, it is possible to use Tiedan, sulfurized smoke and so on. The adhesion amount of the red pigment is within the range of 0.05 to 0.70% by weight for the above-mentioned two kinds of phosphors. -5- This paper scale uses the Chinese 掳 楳 quasi (CNS) A 4 specifications (210X297) 201359 A 6 B6 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Invention description (4) is preferred, especially the range of 0.10 to 0.50 weight X is the best. [Function] So far, europium-activated 〇3 phosphors have been used for a period of time as a red powder for the color brown tube of the Dusting method (Dusting), but they are currently applied in the paste coating of the fluorescent surface preparation method currently used. In the method of coating the slurry, its chemical properties are slightly unstable, and it is not easy to recycle. In addition, because the adjustment range of color tone is extremely narrow compared with Eu-activated Ln2〇2S phosphor, it is now fully activated by Ei! Ln2 02 S Replaced by phosphors, etc. If the Eu concentration is changed from 3 to 4 moles S before; to 8 moles! I; When, E u activates L η 2 0 3 The phosphor can change the color tone to a certain degree as shown in FIG. 3. Here, the so-called europium concentration falsely means that E u activates U 2 0 3 phosphor composition (Lm-s Eua) 2 〇3 of 100a mole 3ί, and the same applies below. However, as compared with the Eu activation L η 2 0 2 S phosphor shown in Fig. 4, it can be seen that the degree of color change is small. The present inventors focused on the characteristics of slight luminous color change and high luminous brightness retention of Eu-activated Ln2 〇3 phosphor, as well as the large luminescent color change caused by the Eu concentration of Eu-activated Ln202 S phosphor Characteristics and relatively low luminous brightness characteristics are adjusted by mixing Eu-activated Ln2 03 phosphor with X value in the range of 0.630 to 0.652 and Eu-activated Ln2 02 S phosphor with X value in the range of 0.652 to 0.674 The unexpected effect of solving the above problems was found for red light-emitting compositions having an X value in the range of 0.647 to 0.662. -6- (please read the precautions on the back before filling in this page) This paper size is easy to use China National Standard (CNS) A 4 specifications (210X297 mm) 81. 5. 20,000 (1) 201359 A 6 B6 Ministry of Economic Affairs Printed by the Central Bureau of Standards Employees Consumer Cooperative V. Description of the invention (5) In order to obtain the above red luminous composition, the concentration of europium should be in the range of 2.08 to 8.0 mol%, preferably Eu in the range of 3.0 to 6.0 mol% A mixture of activated rare-earth vaporized phosphors and Eu-activated rare-earth vaporized sulfide phosphors in the range of 4.0 to 8.0 mol%. Once the mixture is in a weight ratio (rare-earth vaporized phosphors) Body / rare earth gas sulfide phosphor) in the range of 85/15 to 25/75, especially the mixing weight ratio (rare earth vapor gas phosphor / rare earth gas sulfide phosphor) is 50/50 to 70/30 is the best. On the other hand, the conventional Eu-activated Ln203 phosphor that has not been insolubilized will dissolve in the coating and produce hydrogen hydride, resulting in an increase in P # value, and at the same time, the phosphor will be aggregated or the viscosity of the paste will continue to increase. Reasons for changes in the physical properties of the paste. In addition, the changes in the pH of the phosphor paste and the changes in the viscosity prevent the formation of fine-pitch pixels (graphs, lines) with thick filling and excellent shape, which brings many bad effects to the quality of the fluorescent film. Therefore, in the present invention, since the EU-activated LD 2 0 3 phosphor surface is subjected to insolubilization treatment, the chemical stability in the coating paste is improved, and the stability to the coating paste and the coating stability are ensured. The above red light emitting composition. The insolubilization treatment agent used in the present invention is a silicon gas row composed of a two-gasified silicon row or a silicon-containing organic compound, a coating agent such as a zinc aluminate row, a hydrophilic acrylic resin or styrene butadiene It is preferable that the vinyl resin is coated with at least one of the phosphor surfaces. -7- (Please read the precautions on the back before filling in this page) 装--9 · Thread · This paper standard is used in the B family standard (CNS) A 4 specifications (210X297 mm) 81. 5. 20.000 (H ) Λ G Β6 201359 V. Description of the invention (6) The following is a detailed description of the case of representative example Y of Ln, but the invention is not limited to this case. If the relationship between the chromaticity (X value) and the brightness of Eu-activated Y2 03 phosphor and Eu-activated Y2 02 S phosphor is drawn on the same standard, it can be seen that Eu activates Υ2 03 fluorescent as shown in FIG. 1 The change range of the hue of the body is that the X value is 0.630 to 0.652, which is smaller than that of the Eu-activated Υ2 02 S phosphor. However, when the brightness is compared with the same chromaticity (that is, the X value), it will display about 10 to 20¾ High value. The present invention combines Eu-activated 03 phosphor with excellent brightness and darker hue, in other words, Eu-activated Υ2 03 S phosphor with a large X value, and can obtain the X value 0.647 required for the expansion of the range of color reproduction. The shades of red within the range of 0.662 emit light, and activate the Y 2 0 2 S phosphor compared to the previous Eu, and even increase the brightness compared to when the phosphor with these pigments alone is used. From the above combined effect, it can be seen that if Eu with X value 0.643 and brightness 138% activates Y2O3 phosphor (point A) and Eu with x value 0.662, brightness 101¾ activates Y2 02 S phosphor (point B) When the amount is mixed, a red luminous composition with an X value of 0.652 and a brightness of 128% (point C) can be obtained, such as the Y2 02 S phosphor activated with Eu of the same chromaticity (Eu activation amount 4.0 mole%, X value 0.652, Relative brightness 112%) alone, you can see a brightness increase of about 8¾. In addition, the red light-emitting composition belongs to the hue field currently in use. The above is tested in combination with phosphors without pigments attached, but the same effect is also achieved for phosphors with pigments attached. Among them, especially the combination of unused paper standards for the use of national B standard (CNS) A4 specifications (210X297 public funds) (please read the precautions before writing this page) Printed by Beigong Consumer Cooperative A 6 B6 201359 V. Description of the invention (7) (Please read the precautions on the back before writing this page) Eu Activation Y2 with pigments 02 Eu Activation Y2 with phosphors and unattached pigments 〇3 The red light-emitting composition of the phosphor is the most excellent. In the Eu-activated Y2 〇2 S phosphor that requires contrast enhancement, local red pigments such as Tiedan can locally reduce the internal light absorption of the mixed row and obtain a further increase in brightness. However, by attaching red pigments such as Tiedan or the like to the Y2 02S phosphor and the Eu203 phosphor to the Ειι, it is possible to obtain a fluorescent film that is more uniform and has a single solid adhesion than when it is attached unilaterally. So as a Brown tube is more ideal. The adhesion amount of the red pigment of the present invention is preferably in the range of 0.05 to 0.70% by weight for the above two phosphors, particularly preferably in the range of 0.10 to 0.50% by weight. In addition, the Eu-activated Υ2 02 5 fluorescent system uses a luminescent color with an X value of 0.652 to 0.674, but the Eu-activated amount at this time is 4 to 8 mol%. Printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs, if the red paint is attached to the phosphor, it will move to the long wave side (the side with the larger X value), so if you want to obtain the same luminescent color, you can also activate the Eu Decrease 0 to 0.5 mole S; also, the luminescent color can be turned into a deeper red field with the same activation amount of Eu. That is, when the red stripe pigment is not attached, the Eu activation amount is 4.0 to 8.0 moles: ", when there is a red pigment with a shame, it is 3.5 to 8.0 moles S; preferably, it is preferably 3.8 to 8.0 The molar% range is most suitable for maintaining the balance of luminous color and brightness. In addition, the Eu-activated Y2 03 phosphor uses a luminescent color with an X value in the range of 0.630 to 0.652, but the Eu-activated amount at that time is 2 to 8 -9- This paper standard uses the Chinese National Standard (CNS) A4 specifications (210X297 g *) 81. 5. 20.000 (H) 201359 A 6 B6 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of invention (8) Mohr S :. If red phosphor pigment is attached to the phosphor, it will move slightly to the long-wave side (the side with the larger X value), so to obtain the same luminous color, the activation amount can be reduced by 0.03 to 0.15 mol%. , In the same 'Eυ activation amount can also change the luminescent color to a slightly darker red area. In other words, when the red paint is not attached, the Eu activation amount of 2.0 to 8.0 moles of pigment is preferred, especially in the range of 3.0 to 6.0 mole%; and when the red stripe pigment is attached, From 2.0 to 8.0 moles 3; preferably, from 285 to 6.0 mole% is the best. As described above, in the present invention, by adhering the red phosphor pigments to the two types of phosphors respectively, the maximum value of the luminous color (X value) can be obtained by 0.670, which is about 0.008 greater than 0.662 when not attached. The effect of the above invention. To obtain the red light-emitting composition, it is advisable to set the mixing weight ratio (Υ 2 〇3 phosphor / Y2 〇2 S phosphor) at 85/15 to 25/75. If the mixing weight ratio exceeds 85/15, the color The reproduction deteriorates, and if it falls below 25/75, the effect of increasing the brightness is insufficient. In addition, the optimum range of the mixing weight ratio is 50/50 to 70/30. The red light-emitting composition thus obtained has a luminous intensity ratio of 626 nm and 611 nm / λ of luminous peaks of Eu activated yttrium gas sulfide phosphor and Eu activated yttrium gas sulfide phosphor in the range of 0.2 to 3.0 . 626 611 [Example] After dissolving 226g of vaporized yttrium and 14.1g of vaporized europium with hydrochloric acid, co-precipitated oxalate is made from oxalic acid, which is decomposed by 1000¾ to get -1 0-(please read the precautions on the back first (Fill in this page) This paper uses the Chinese National Standard (CNS) A4 specifications (210x297 g *) 81. 5. 20,000 (H) 201359 A6 B6 V.

This phosphor component was subjected to dispersion treatment with a ball mill, and then surface-treated with zinc aluminate coating material and dried and trimmed. Then, Ge02 was mixed as a pH increase inhibitor in a dry state of 0.4¾ to obtain phosphor component A. On the other hand, to correct the chromaticity of the above-mentioned phosphor component A, a 02 S: Eu (Eu, 4.8 mol%) phosphor component B with a deeper chromaticity, that is, a thicker europium concentration was prepared. Then, these phosphor components were mixed at a mixing weight ratio (A / B) of 1/1 to obtain the red light-emitting composition of Example 1. The characteristics of these red light-emitting compositions and the above-mentioned mixed components were measured under the condition of ZOkVJ.Ow A / cm2 using a removable electronic wire excitation device, as shown in Table 1, and the red color of Example 1 The previous Y2 〇2 S: Eu (Eu, 4.0 mol; C) phosphor comparison result of the same luminous chromaticity of the luminescent composition, the relative brightness increases by about 7¾ and becomes brighter. In addition, the above red luminescent composition was slurried and coated on the panel with P V A-C r Shito photosensitive solution, and the brightness of the completely red Brown tube was measured. As a result, the relative brightness increased by about 8¾ and became bright.
