精细陶瓷（先进陶瓷、先进技术陶瓷） 白光发光二极管用陶瓷荧光粉光学性能标准材料测试方法

[中文适用范围]： 本文件规定了一种替代测量方法，用于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、外部量子效率和吸光度，这些荧光粉在受紫外光或蓝光激发时会发出可见光。在该方法中，使用市售的测量设备（例如配备单色光源作为入射光的荧光分光光度计或光谱辐射计）测量参考材料的荧光光谱，参考材料的量子效率和吸光度已使用 ISO 23946 中的方法确定，并且被测荧光粉材料也已确定。 [外文原描述]： This document specifies a substitution measurement method to measure internal quantum efficiency, external quantum efficiency and absorptance of ceramic phosphor powders, which are used in white light-emitting diodes (LEDs) and emit visible light when excited by UV or blue light. In this method, commercially available measurement equipment, such as a fluorescence spectrophotometer or a spectroradiometer equipped with a monochromatic light source as incident light, are used to measure fluorescence spectra for reference materials whose quantum efficiencies and absorptance have been determined using the methods in ISO 23946 and a phosphor material under test.
