摘    要:采用共沉淀法成功合成了Y(P,V)O4:Eu^3+荧光粉,并利用SEM、变温紫外激光激发及真空紫外激发下的发射光谱对所合成粉体的表面形貌及发光性能进行了表征。试验结果表明,与高温固相合成法相比,共沉淀法合成的Y(P,V)O4:Eu^3+荧光粉的颗粒形貌好,发光强度明显提高;在325nm激光激发下,低温时存在基质VO4^3-的蓝色宽带发射,随着温度升高,VO4^3-吸收的激发能量逐渐传递给Eu^3+,使其发光逐渐增强,当温度高于临界点时,Eu^3+发射出现温度猝灭;Y(P,V)O4:Eu^3+荧光粉发射主峰位于619nm,色纯度好,且发光亮度与彩色PDP用商品红粉(Y,Gd)BQ:Eu^3+相当。

关 键 词:共沉淀法  PDP  荧光粉  光谱

Abstract:Y(P, V)O4 :Eu3+ phosphors with good morphology for plasma display panels have been prepared via coprecipitation reaction. The phosphor was characterized by SEM and photoluminescence under UV(325 nm)and VUV(147 nm) excitation. The emission spectra depending on temperature under 325 nm excitation by laser indicated that there exist energy transfer between VO43- group and Eu3+ ion. Under 147 nm excitation, the most intense emission peaks of commercial (Y,Gd)BO3 :Eu3+ phosphor range around 593 nm, and those of Y(P, V)O4, :Eu3+ phosphors prepared by coprecipitation reaction ranged around 619 nm. The red emission color purity of Y(P,V)O4 :Eu3+ phosphor is much better than that of (Y,Gd)BO3 :Eu3+ , and its relative emission intensity is almost close to that of the commercial phosphor.
Keywords:Coprecipitation   PDP   Phosphor   Spectrum
