精细陶瓷（高级陶瓷、高级技术陶瓷） 用积分球测定白色发光二极管用陶瓷荧光粉光学性能的试验方法

[中文适用范围]： 本文件规定了使用积分球测量陶瓷磷光粉光学性能的测试方法。这些陶瓷磷光粉用于白色发光二极管（LED），并在受到紫外光或蓝光激发时发射可见光。 本文件规定了一种绝对法测量内量子效率，以及一种替代法测量外量子效率和吸收率。 替代法使用参考材料，其外量子效率和吸收率是根据ISO 23946获得的。 [外文原描述]： This document specifies test methods for the use of an integrating sphere to measure the optical properties of ceramic phosphor powders, which are used in white light-emitting diodes (LEDs) and emit visible light when excited by UV or blue light. This document specifies an absolute method to measure internal quantum efficiency and a substitution method to measure external quantum efficiency and absorptance. The substitution method uses reference materials whose external quantum efficiency and absorptance have been obtained in accordance with ISO 23946.
