本文件规定了一种替代测量方法，用于测量陶瓷荧光粉的内部量子效率、外部量子效率和吸收率，陶瓷荧光粉用于白光发光二极管（LED），当受到紫外光或蓝光激发时会发射可见光。在该方法中，使用市售的测量设备，例如配备有单色光源作为入射光的荧光分光光度计或分光辐射计，来测量其量子效率和吸收率已使用ISO？23946和被测磷光体材料。

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.
