摘要：
Time-resolved photoluminescence was used to study exciton recombination in deep CdTe/Cd0.5Mn0.5Te single quantum well. The width of the investigated well was 100 Angstrom. The study was performed at room temperature. The lifetime of the exciton determined in this work has a value comparable to that observed in shallow CdTe/Cd0.85Mn0.15Te quantum wells. A strong enhancement of the photoluminescence decay time with increasing intensity of the exciting laser beam is observed which is indicative of saturation of the non-radiative recombination centers.
