半导体器件第5-10部分:光电子器件发光二极管基于室温基准点的内部量子效率试验方法

[中文适用范围]： 本文件规定了无磷光体的单个发光二极管（LED）芯片或封装的内部量子效率（IQE）的测量方法。照明应用的白光LED不在本文件的范围内。本文件仅使用在操作室温下测得的相对外量子效率（EQE）。为了确定参考IQE，找到对应于100%注入效率的操作电流，并通过该点相对EQE的无穷小变化确定辐射效率。IQE随电流的变化是根据EQE值与称为室温参考点法（RTRM）的参考点值的相对比值计算得出的。 [外文原描述]： IEC 60747-5-10:2019(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 only the relative external quantum efficiency (EQE) measured at an operating room temperature. In order to identify the reference IQE, an operating current corresponding to the injection efficiency of 100 % is found and the radiative efficiency is determined by the infinitesimal change of the relative EQE at that point. The IQE as a function of current is then calculated from the relative ratio of the EQEs to the value at the reference point, which is called room-temperature reference-point method (RTRM).
