摘　　要：在自行研制的测试仪器的基础上，用增加激发光总量检测和荧光粉表面漫反射光检测，两者相减获得绝对吸收的方法改善荧光粉在120～300nm紫外一真空波段的相对量子效率测量精度。总量检测通过一块漫反射板标定实现，给出了标定和测量过程。改进后相埘量子效率测量误差减小到1％以内，同时利用该方法获得了较为精细的激发光谱曲线，光谱分辨率达到1nm。对BaMgAI10O17Eu蓝色荧光粉和LaOO4：Tb、LaPO4：CeTb以及YPO4：Tb三种绿色荧光粉激发光谱进行了测量。In order to improve the measurement precision of relative quantum efficiency of the phosphors in 120~300 nm,the surface diffuse reflection intensity and the excitation light total intensity of phosphors were measured,and the difference between the two values was the real absorbed intensity. The total excitation intensity was obtained by calibrating a diffuser. Thus relative quantum efficiency precision of phosphors for Plasma Display Plane（PDP） in UV-VUV ranging from 120 nm to 300 nm was improved. Experimental result shows that the measurement precision is below 1%, and the comparative fine excitation spectral curve is obtained, the spectral resolution is 1 nm. At last, excitation spectra of blue phosphors（BaMgAl10O17 ：Eu） and three kinds of green phosphors （LaPO4 ：Tb,LaPO4 ： CeTb ,YPO4 ：Tb） were measured.
