The quantum well spectra were explained in terms of the radiative recombination of excitons in the localized states. Exciton formation of the InGaN MQW might he delayed for excitations above the GaN barrier excitation compare with exciton formation in excitations below the GaN barrier. The critical temperature at which nonradiative recombination dominantly occurred was increased under the excitation below the GaN barrier because screening caused by carriers in the GaN barrier vanished.
