摘要
本文研究了采用高温固相法合成的Ba3Gd(PO4)3:Dy3+荧光粉的阴极射线发光特性。测试并比较了电子轰击前后荧光粉的CL谱、色坐标以及PL谱变化。Ba3Gd(PO4)3:0.06Dy3 +荧光粉的色坐标为x =0.454 ,y =0.424 ,Tc=2889.3K。测试结果显示该荧光粉是一种低色温、暖白光荧光粉,并且具有高的饱和电流,有耐大电流密度电子束轰击的能力。
Cathodoluminescent properties of Ba3Gd（PO4）3 ：Dy^3＋ phosphor were studied. The phosphor was synthesized by high-temperature solid-phase reaction. Cathodoluminescence spectra, the Commission In- ternational de l＇Eclairage colour coordinates and photoluminescence spectra were determined. The Cathodoluminescence measurement shows that the Commission International de l＇ Eclairage （CIE） chromaticity coordinates of Ba3Gd（PO4）3：0.06Dy^3＋ phosphor are x=0. 454 and y=0. 424, and the color temperature is 2889.3 K. The results show that the phosphor is a low color temperature, warm-white phosphor with high saturation currents and can endure high-current-density bombardment.
