摘要

摘要：发射光谱、相对亮度和激发光谱特性是大屏幕显示用荧光粉研究中重要的参考指标，发射光谱测量方法相对单一，测量精度和重复性容易保证在1％以内，但相对亮度和激发光谱受测量方法的影响，测量精度和重复精度难以达到1％的要求。本文在自行研制的测试仪器基础上，通过荧光粉表面漫反射光检测的方法改善荧光粉在120nm-300nm紫外-真空波段的相对量子效率测量精度，将相对量子效率测量误差减小到1%以内，同时利用该方法获得较为精细的激发光谱曲线，光谱分辨率达到1nm，对BaMgAl10O17：Eu蓝色荧光粉，LaPO4:Tb、LaPO4:CeTb以及YPO4：Tb绿色荧光粉激发光谱进行了测量。

Abstract

Abstract：Emission spectra

relative luminance and excitation spectra characteristics are important factors in the field of phosphors research. Measurement of emission spectra is relative simple

its precision and repeatability can be ensured within 1% more easily

but relative luminance and excitation spectra is difficult to have precision and repeatability of 1% affected by test method. In this article

one method that phosphors surface diffuse reflection intensity is measured to improve relative quantum efficiency accuracy of phosphors for PDP in UV-VUV range between 120nm to 300nm

the relative quantum efficiency measuring precision is below 1% and the comparative subtle excitation spectrum curve is obtained

the spectra resolution is 1nm. At last

the measurement of excitation spectrum of (BaMgAl10O17：Eu) blue phosphors and (LaPO4:Tb

LaPO4:CeTb

YPO4：Tb )three green phosphors is taken.
