标准摘要
[中文适用范围]： 本文件规定了使用测角分光荧光计测量白光发光二极管（LED）中发射可见光的陶瓷荧光粉粉末的内量子效率、外量子效率、吸收率、发光辐射系数和相对荧光光谱的方法。 受到紫外线或蓝光激发时发出光。 [外文原描述]： 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.
英文名称Fine ceramics (advanced ceramics, advanced technical ceramics) — Test methods for optical properties of ceramic phosphors for white light-emitting diodes using a gonio-spectrofluorometer
