Abstract Nanostructured Copper Selenide thin films has been fabricated using a simple chemical synthesis process of chemical bath deposition method. The concentration of complexing agenthas a vital role that effect on the stoichiometry and control basic parameters in related to semiconductor materials. The nanoparticles, the Copper Selenide thin films configuration, and the energy band gap as well as thickness of thin films are optimized considering experimental data and using proper governing last solution pH at optimized temperature. XRD is used to characterize the thin films, energy band gap is estimated by UV-visible spectroscopy. In addition, the quantitative analysis of the thin films is carried out using EDX technique, and surface morphology is examined by field emission scanning electron microscopy (FESEM). The EDX data show that stoichiometry of samples optimum with increasing of the complex agent concentration, sample with pH = 10 has an optimal stoichiometry. From the present work for producing the appropriate CuSe nanostructure thin film, which can be used in quantum dot solar cell. Nanostructured natural of thin films empower for their outstanding photo-catalytic behavior due to the role from the increased visible light absorption.

化学溶液沉积法制备硒化铜的光学和光催化特性的调整

摘要 采用化学浴沉积法这一简单的化学合成工艺制备了纳米结构的硒化铜薄膜。络合剂的浓度对半导体材料的化学计量和控制基本参数起着至关重要的作用。纳米颗粒、硒化铜薄膜配置、能带隙以及薄膜的厚度都经过优化，考虑到实验数据并在优化温度下使用适当的控制最终溶液的 pH 值。XRD用于表征薄膜，能带隙通过UV-可见光谱估计。此外，使用 EDX 技术对薄膜进行定量分析，并通过场发射扫描电子显微镜 (FESEM) 检查表面形态。EDX 数据表明，随着复合试剂浓度的增加，样品的化学计量最佳，pH = 10 的样品具有最佳的化学计量。从目前生产合适的 CuSe 纳米结构薄膜的工作来看，可用于量子点太阳能电池。由于可见光吸收增加的作用，纳米结构的天然薄膜使其具有出色的光催化性能。
