Description
Technical field
The present invention relates to fluorescent material, and in particular to a kind of high luminescent phosphor and method.
Background technology
In the prior art, LED development is using white light LEDs and high-brightness LED as main developing direction, and white light LEDs have
Small volume, environmental protection, caloric value and power consumption are low, the illumination source as the new generation.
The development of white light LEDs is with the O 12 of 3 Al of blue light indium gallium nitride LED Y 5：Ce；YAG：Ce yellow) is glimmering
Light powder.YAG fluorescent powder is absorbed after the light of 450~470nm wavelength (blue spectral range), can produce 550~560nm wavelength
Light, utilize the principle that blue light and gold-tinted are complementary coloured light, mixed light produces high-brightness white-light.Using YAG fluorescent powder collocation blue light
LED chip is still that current industry is the most frequently used one of in the way of manufacturing white light LEDs, and this white light LEDs have cost low and power supply
The advantages of loop configuration is simple.YAG fluorescent powder is given out light compared with the red of shortcoming, the white light LEDs processing procedure of addition red light fluorescent powder into
The direction being directed to for industrial circle.
The content of the invention
It is an object of the present invention to for the drawbacks described above of prior art, there is provided a kind of high luminescent phosphor and its preparation
Method, the white light LEDs of addition red light fluorescent powder have higher brightness and luminous efficiency, further improve white light LEDs
Luminous efficacy.
A kind of high luminescent phosphor is provided, based on deal, is mixed using llowing group of materials：
1) the green powder of rare earth (Ce, Tb) MgAl11O19,10-30 part；
2) blue powder (Ba, Mg, Eu) 3Al16O27,20-50；
3) rouge and powder Y2O3：Eu3+, 30-60 parts.
A kind of method for preparing above-mentioned high luminescent phosphor is provided, the wherein fluorescent material has following chemical formula：
M2ZF6：Mn 3+；
Wherein M is the alkali metal selected from sodium or potassium, and Z is the triad selected from silicon or titanium, and preparation process is as follows：
A1, the first solution is first prepared, the first solution includes triad, by Z oxide, hydroxide or carbonate and should
Manganese compound, is dissolved in hydrofluoric acid solution and is formed；
A2, the second solution of preparation, alkali metal M compounds, using sulfate, carbonate, nitrate, hydroxide, fluorination
Thing or hydrofluoride are dissolved in hydrofluoric acid solution and formed；
A3, first solution is mixed and alkali metal M compound is reacted, to form sediment；
A4, addition acetone are in the first solution；Collect the sediment of the first solution；The addition of acetone be the first solution and this
50-100 parts of the cumulative volume sum of two solution；
A5, by the green powder of rare earth (Ce, Tb) MgAl11O19, blue powder (Ba, Mg, Eu) 3A116O27, rouge and powder Y2O3：In Eu3+ additions
State in sediment, after stirring, high luminescent phosphor is made.
Rare earth element is introduced fluorescent material by the present invention, the luminescent properties of fluorescent material is significantly improved.The green powder of rare earth
(Ce, Tb) MgAl11O19, blue powder (Ba, Mg, Eu) 3A116O27 and rouge and powder Y2O3：Eu3+.And mix them by a certain percentage
Close, tricolor powder has been made.Can be made into tricolor powder colour temperature (i.e. black body radiation same or like with light source color when reached
Temperature) be 2300~8000K various three-color fluorescent lamps.The luminous efficiency of general three-basic-colour lamp is 90~100lm/W, is shown
Colour index is 85~90.It can be seen that the luminous efficiency and colour rendering index of three-basic-colour lamp have very big carry than halogen-phosphate fluorescent lamp
It is high.The anti-ultraviolet aging of tricolor powder, high temperature, high-intensity ultraviolet irradiate stability inferior height and specular removal, high-color rendering etc.
Advantage, can be made into the various compact type lamps such as U, H.This lamp small volume, caliber are thin, and ultraviolet flux ratio ordinary straight lumiline lamp is high to be obtained
Many, tube wall temperature is high.Halogen-phosphate fluorescent material can not meet these requirements.The appearance of compact type lamp opens the new way of economize on electricity
Footpath, is described as third generation light source.This lamp is compared with general lamp, and when light is logical identical with colour rendering index, the energy that it needs is
The 1/4 of ordinary lamps, and the life-span is then 5 times of ordinary lamps.
In order to further improve the luminescent properties of rare-earth trichromatic powder, Y2O3：Eu3+, because yittrium oxide is expensive, green powder (aluminium
Hydrochlorate is in the majority), because the quantum efficiency of general green powder only has 80%, therefore primarily with regard to the research for improving luminous efficiency.With (Ce,
Tb) exemplified by MgAl11O19, Ce3+ transmitting (360nm) and Tb3+ absorption (340nm) is made to have best weight by changing component
It is folded, so as to increase Ce3+ → Tb3+ energy transmission.And make Ce3+ absorption maximum (280nm) blue shift, be allowed to and mercury line spoke
Penetrating (254nm) has more preferable matching.Blue powder in rare-earth trichromatic powder is with the Eu2+ aluminates activated or halogen-phosphate.Pass through
Change component adjustment photochromic, to improve the colour rendering of three-basic-colour lamp.General three-basic-colour lamp colour rendering index is 82~84, is had during lighting
Yellow sense.Because the colour rendering index of three-basic-colour lamp is significantly influenceed by the emission peak of blue powder, so when its emission peak of change
When being worth for 470~500nm (bluish-green powder), the colour rendering of three-basic-colour lamp can obtain obvious improvement.
After testing, the fluorescent material that the present invention is provided, can reach following technical indicator：
| Illuminator type | Initial lumen/lumen | Colour rendering index |
| Broad-band illumination powder | 2200 | 90 |
| Arrowband is three primary colors luminous | 3200 | 73~80 |
| Four primary luminescent powder | 2925 | 90 |
