中文摘要	we have investigated spin polarization-related localized exciton photoluminescence (pl) dynamics in gainnas quantum wells by time-resolved pl spectroscopy. the emission energy dependence of pl polarization decay time as well as polarization-independent pl decay time suggests that the acoustic phonon scattering in the process of localized exciton transfer from the high-energy localized states to the low-energy ones dominates the pl polarization relaxation. by increasing the excitation power from 1 to 10 mw, the pl polarization decay time is changed from 0.17 to more than 1 ns, which indicates the significant effect of the trapping of localized electrons by nonradiative recombination centers. these experimental findings indicate that the spin-related pl polarization in diluted nitride semiconductors can be manipulated through carrier scattering and recombination process.
