用非相干光时间延迟四波混频测量载流子复合时间
Measurement of Carrier Recombination Time Using Time-Delayed Four-Wave Mixing with Incoherent Light
【摘要】 本文首次报道了用非相干光时间延迟四波混频测量载流子复合时间的理论,实验证实了该理论的正确性,测得PbS超微粒子和CdS:Cu的载流子复合时间分别为1.56ns和0.8ns
【Abstract】 Abstract We present a theory of measuring carrier recombination time using Time-Delayed Four-Wave Mixing with Incoherent Light. The expriments showed the validity of the theory. We obtained the carrier recombination time of PbS ultrafine particles and CdS:Cu. The investigation suggests that the decay time of the largeperiod grating is longer than that of the small one for PbS ultrafine particles in organosols and CdS:CU.
