Abstract
Room temperature photoluminescence spectra from a ZnCdSe single quantum well have been measured as a function of time in a minute time scale under several photoexcitation levels (4–40 W/cm2). Spectrally integrated photoluminescence intensity increases as the measurement time increases and reaches a maximum level that is 37 times higher than the initial intensity. We attribute this dynamical behavior to recombination-enhanced defect reactions in the vicinities of point defects. These reactions reduce the density of point defects and enhance radiation quantum efficiency. A new point defect reduction rate was discovered to fit our experimental data.
