钒硼酸钇铕荧光粉的真空紫外光谱特性研究

VUV characteristics of yttrium borate vanadate phosphor

采用高温固相法合成了YBxV1-xO4-x∶Eu3+荧光粉,利用XRD变温发射光谱以及真空紫外激发的光谱对其进行研究。结果表明,在147nm的真空紫外光激发下,荧光粉的发射主峰位于619nm,与(Y,Gd)BO3∶Eu3+相比,色纯度较好,发光亮度达86%,是彩色PDP用红色荧光粉的候选材料。

YBχV1-χO4-χ：Eu^3＋ phosphors were prepared by solid state reaction. The red emission color purity of YBχV1-χO4-χ：Eu^3＋ phosphor was much better than that of the recent widely-used commercial red emitting phosphor （Y,Gd）BO3：Eu^3＋ and its relative emission intensity was 86% of the commercial phosphor （Y,Gd） BO3：Eu^3＋. It was expected that YBχV1-χO4-χ：Eu^3＋ phosphor would be a promising candidate for PDP （plasma display panels） application.
