中文摘要：

采用超声喷雾法制备了硫化铟（In2S3）薄膜，并考察了后续快速热处理（rapid thermal process，RTP）对硫化铟薄膜性能的影响。采用扫描电镜（SEM），X射线衍射（XRD）等手段对薄膜的形貌、结构、透射率等性质进行了表征。结果表明：超声喷雾法制备的In2S3薄膜均匀致密，采用RTP热处理可提高薄膜的结晶性能，但对薄膜的透光性影响较小。通过计算可以得出薄膜的禁带宽度约为2．25—2．38eV。

英文摘要：

The In2S3 films have been prepared by ultrasonic spray pyrolysis technique. The morphology, structure and optical transmittance of InzS3 films have been characterized by XRD, SEM and speetrophotometer. The influence of post deposition annealing temperature on the film properties were studied. The results show that uniform and compact In2S3 films can be obtained by ultrasonic spray pyrolysis method. The post RTP can enhance crystallization of the In2S3 films with weak influence on optical transmittance. The band gap of the InzS3 thin films is about 2.25 - 2.38 eV.
