## Abstract We studied the nonthermal mechanism of quantum efficiency (QE) roll‐off in InGaN‐based multiple‐quantum‐well LEDs on sapphire and bulk GaN substrates with In content ranging from 1% to 28%. Both the efficiency evolution and peak energy shift appear to be strongly dependent on the In con
