非晶态硒化镉瞬态光致发光特性

Transient Photoluminescence in Amorphous CdSe

研究了非晶态硒化镉薄膜时间分辨光致发光强度随时间的衰减和发光峰值能量随时间的变化，用载流子成对模型分析了光生载流子的热释和辐射复合初始动力学过程．

Time-resolved photoluminescence (PL) deary and peak energy shift with time of PL emission spectrum in amorphous CdSe. are Studied. The initial dynamics of the thermalization and radiative recombination of photogenerated carriers are analysed with the geminate-pair model.
