摘要
采用溶胶凝胶法和自旋镀膜法制备cu2 - znsns4薄膜，胸部x线医学影像被广泛用于诊断。本文研究了cu2 znsns4薄膜的结构和光学等物理性质。制备的薄膜在氮气气氛下400℃退火1h。(112)、(220)和(312)的28.31°、47.26°和56.12°峰的XRD谱图证实了制备的cu2 znsns4薄膜均具有kesterite结构。XRD谱图和紫外可见光谱结果表明，该材料在可见光区具有较大的光吸收系数，大于10 5 cm -1。根据光学特性，估计出等于Eg≈1.5 eV的带隙
Structural and Optical Properties of Cu2ZnSnS4 Films Prepared by Sol-Gel method
Chest x-ray medical images are widely used for diagnostic purposes for Cu 2 ZnSnS 4 thin films are prepared by sol gel and spin coating methods. In this study, some physical properties such as structural and optical properties of Cu 2 ZnSnS 4 thin films are investigated. Prepared thin films are annealed at 400°C for 1 h under N 2 atmosphere . XRD pattern for the peaks 28.31°, 47.26°, and 56.12° which have indexed plans (112), (220) and (312) confirmed that all Cu 2 ZnSnS 4 thin films prepared have kesterite structure. The results of XRD patterns and UV– Visible spectra demonstrated kesterite phase and a great optical absorption coefficient more than 10 5 cm -1 in visible region. The estimation of the band gap which equal Eg ≈ 1.5 eV by dependent at the optical characteristics
