摘要：

In2S3 thin films have been deposited onto glass substrates at 340 degrees C using an inexpensive spray pyrolysis method (CSP) via the reaction between high purity indium chloride and thiourea. Structural, optical and photoconductive properties of thin films have been investigated by adjusting S/In molar ratio. The X-ray diffraction results revealed that In2S3 films are polycrystalline and exhibited a cubic structure. The optical and morphological properties are discussed. The photoconductive performances were conducted by DC electrical characterization. The best photosensitivity was obtained for the film matching S/In = 2 molar ratio. In addition, photocurrent versus light intensity and bias voltage follows a power law and linear trend, respectively. Furthermore, some critical parameters such as responsivity and detectivity were determined to evaluate photosensitive properties of In2S3 thin films.
