Abstract This study reviews ZnO, NiO, and ZnO/NiO nanocomposites thin films deposition using the Spray Pyrolysis Technique (S.P.T). The thin films were deposited onto ordinary glass substrates heated at 500 °C from aqueous solutions of zinc chloride and nickel chloride precursors dissolved in distilled water. The structural, morphological, and optical properties of the ZnO, NiO, and ZnO/NiO thin films have been studied by X-ray diffraction, scanning electron microscopy, Raman spectroscopies, and so on. The optical band gaps are 3.3 and 3.5 eV for ZnO and NiO thin films, respectively obtained by UV–Vis spectroscopy. However, the optical band gaps of ZnO/NiO nanocomposites thin films, are noticeable out of the range (3.4–3.64 eV). GRAPHICAL ABSTRACT

喷雾热解ZnO/NiO纳米复合薄膜的简便合成

摘要 本研究回顾了使用喷雾热解技术 (SPT) 沉积 ZnO、NiO 和 ZnO/NiO 纳米复合材料的薄膜。将薄膜从溶解在蒸馏水中的氯化锌和氯化镍前体的水溶液沉积到在 500°C 下加热的普通玻璃基板上。已经通过 X 射线衍射、扫描电子显微镜、拉曼光谱等研究了 ZnO、NiO 和 ZnO/NiO 薄膜的结构、形态和光学性质。通过紫外-可见光谱法获得的 ZnO 和 NiO 薄膜的光学带隙分别为 3.3 和 3.5 eV。然而，ZnO/NiO 纳米复合薄膜的光学带隙明显超出范围 (3.4–3.64 eV)。图形概要
