标准范围

本文件规定了一种使用gonio荧光光谱仪测量白色发光二极管(LED)中使用的陶瓷荧光粉的内部量子效率、外部量子效率、吸收率、发光辐射系数和相对荧光光谱的方法,该陶瓷荧光粉在紫外光或蓝光激发下发出可见光。

This document specifies a method for use of a gonio-spectrofluorometer to measure internal quantum efficiency, external quantum efficiency, absorptance, luminescent radiance factor and relative fluorescence spectrum of ceramic phosphor powders which are used in white light-emitting diodes (LEDs) and emit visible light when excited by UV or blue light.
