Description

A kind of yellow longpersistent fluorescent powder and preparation method thereof
Technical field
The invention belongs to phosphor technologies fields, more particularly to a kind of yellow longpersistent fluorescent powder and preparation method thereof.
Background technique
Long-persistence luminous is a kind of very important luminescence phenomenon, and it is even several to show as a few minutes after stopping illumination to sample In hour, sample still maintains a kind of luminous phenomenon, increasingly attracts people's attention.Originally, long-persistence luminous material Material is applied primarily to safety sign, urgent route sign, traffic sign and night display etc., these subsequent materials are also used for Optical storage medium, radiation detection and structural damage sensor etc., at present again have more and more fields such as Solar use and Vivo biodistribution imaging etc. can use long lad phosphor also to solve relevant issues.The long-persistence luminous material of different substrates series The luminosity spectral characteristic of material is different, due to its luminescent color, luminous intensity, persistence it is different and with different applications before Scape, therefore there are respective advantages.
For the luminescent color that human eye visually perceives long after glow luminous material, it can theoretically pass through mixing The three primary colors of different proportion obtain any color, but due to the limitation of some objective factors, and this method is in practice but It is difficult to fully achieve.So far, the three primary colors long after glow luminous material of commercialization is mainly SrAl2O4: Eu2+, Dy3+ (green), CaAl2O4: Eu2+, La3+(blue) and Y2O2S:Eu3+, Mg2+, Ti4+(red), but the above two persistence is all It has been more than 24 hours, and decay of afterglow time longest yellow longpersistent luminescent material Y2O2S:Eu3+, Mg2+, Ti4+Twilight sunset when Between only 5 to 10 hours, therefore be difficult to be consistent the decay of afterglow process of three kinds of different colours long-afterglow materials, finally lead Cause the unstable of twilight sunset color.In addition, most of long after glow luminous material cannot effectively be excited by identical excitation light source, because This, it is desirable to it obtains stable white or yellow longpersistent and shines, research and development new type long-persistence luminescent material then must can not It is few.In document report in recent years, new type long-persistence luminescent material is still based on green and blue luminescent material, and long wave is sent out The long after glow luminous material penetrated is less, only Sr3SiO5: Eu2+, Dy3+(570nm, 6h), Y2O2S: Sm3+(606nm, 1.5h), Sr3Al2O5Cl2: Eu2+, Tm3+(610nm, 4h), Sr2Si5N8: Eu2+, Tm3+(612nm, 10min), Sr2SnO4: Sm3+(624nm, 1h) and Y2O2S: Eu3+, Mg2+, Ti4+(627nm, 5h) etc. a few, and for yellow For long after glow luminous material, since the wave-length coverage of spectrum is relatively narrow (560-590nm), relevant report is less, therefore, is badly in need of out Send out novel yellow long after glow luminous material some.
Summary of the invention
Yellow longpersistent luminescent material shortage in the prior art, in order to overcome above-mentioned yellow longpersistent in the prior art to shine The problems such as luminous intensity of material is weaker, persistence is shorter, the present invention provides a kind of novel yellow long lad phosphor and Preparation method, the fluorescent powder have many advantages, such as that after-glow brightness is high, persistence is long, can be used for safety sign, urgent route mark The fields such as will, traffic sign and night display.
Since the type of long after glow luminous material is more, different materials has different luminous mechanisms, and some materials Luminescence mechanism be also not clear at present, therefore, seek suitable matrix and active ions opening for new type long-persistence material Send out most important.Further, since the preparation method of long after glow luminous material is more, and there are respective advantage and disadvantage, thus it is right The optimum organization of the preparation method of various long after glow luminous material will also be played the popularization and application of long after glow luminous material and be closed very much The effect of key.
