标准摘要
[中文适用范围]： 本部分国际电工委员会（IEC）60747标准规定了单颗发光二极管（LED）芯片或不含荧光粉的封装的体内量子效率（IQE）的测量方法。照明应用的白光LED不在本文件范围内。本文件利用在低温下和操作温度下测量的相对外量子效率（EQE），称为温度依赖电致发光（TDEL）。为了确定参考IQE为100%，通过改变环境温度和电流来寻找EQE峰值的最大值。 [外文原描述]： IEC 60747-5-9:2019(E) specifies the measuring method of the internal quantum efficiency (IQE) of single light emitting diode (LED) chips or packages without phosphor. White LEDs for lighting applications are out of the scope of this document. This document utilizes the relative external quantum efficiencies (EQEs) measured at cryogenic temperatures and at an operating temperature, which is called temperature-dependent electroluminescence (TDEL). In order to identify the reference IQE of 100 %, the maximum values of the peak EQE are found by varying the environmental temperature and current.
