Semiconductor devices - Part 5-11: Optoelectronic devices - Light emitting diodes - Test method of radiative and nonradiative currents of light emitting diodes
半导体器件第5-11部分:光电子器件发光二极管发光二极管辐射电流和非辐射电流的试验方法
IEC 60747-5-11:2019(E) specifies the measuring methods of radiative and nonradiative currents 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 internal quantum efficiency (IQE) as a function of current, whose measurement methods are discussed in other documents.
