Abstract :
Summary form only given. Semiconductor ZnSe and its heterostructure materials can be developed as blue color light-emitting diodes, lasers and high-speed optoelectronics devices. The investigation of emission time evolution in ZnSe can provide important information for the understanding of emission mechanism and the improvement of the device characteristics. In this paper, we studied the temporal behaviors of stimulated and spontaneous emissions in ZnSe thin film by using time-resolved sum-frequency technique (upconversion) in the femtosecond region.
