摘要

从室温下测量的外部量子效率作为电流的函数来评估高亮度蓝色LED的内部量子效率。采用基于abc模型的新型评估程序对数据进行处理，分别确定了UX:3芯片LED结构的IQE和光提取效率(LEE)。

Novel evaluation procedure for internal and extraction efficiency of high-power blue LEDs

Internal quantum efficiency (IQE) of a high-brightness blue LED has been evaluated from the external quantum efficiency measured as a function of current at room temperature. Processing the data with a novel evaluation procedure based on the ABC-model, we have determined separately IQE of the LED structure and light extraction efficiency (LEE) of UX:3 chip.
