Diffusion-controlled effects of luminescent efficiency in InGaN/GaN light-emitting diodes

Temperature dependence of photoluminescence (PL) and time-resolved photoluminescence (TRPL) were used to investigate the recombination process in InGaN/GaN light-emitting diodes (LEDs). The results exhibited that the nonradiative recombination process can be explained by diffusion-controlled kinetic.
