  • Abstract This thesis used TCSPC (Time-Correlated Single Photon Counting) apparatus to study the time-resolve photoluminescence (TRPL) of InGaN multi-quantum-well light emission diode and the photoluminescence of Zn1-xMgxSe properties at different Mg concentration. We obtained the activation energy form Arrhenius Plot, internal quantum efficiency (IQE), the radiative lifetime, and the radiative recombination critical at 180K of In0.25Ga0.75N multi-quantum well LED. Furthermore, the variation of PL peak location and FWHM with Mg concentration of Zn1-xMgxSe thin film with x=0.1、0.25、0.34、0.37、0.4、0.42 are observed.
