Abstract The interaction between glass surface and forming nanocrystals plays the important role in the formation of thin ZnO coatings crystal structure. The comparative study of the crystal structure of thin ZnO-based films and powders having similar chemical compositions was performed with the use of SEM, XRD analysis, optical, and luminescent spectroscopy. The influence of different coatings parameters (chemical composition, thickness) on the spectroscopic and morphological properties of thin films and powders reveals the structural features of the interaction between forming ZnO nanocrystals and glass surface. ZnO–SnO2 coatings and powders were prepared by liquid polymer-salt technique. This method provides the close contact between the coatings’ precursors with a surface of the glass during both the nucleation and the initial growth stage of forming oxide crystals. The interaction of nanocrystals and substrate surface is responsible for the texture formation in the ZnO films and determines some features of their optical properties.

形成纳米晶体和玻璃表面之间的相互作用对 ZnO 基薄膜结构和性能的影响

摘要 玻璃表面与形成纳米晶之间的相互作用在薄ZnO涂层晶体结构的形成中起着重要作用。使用 SEM、XRD 分析、光学和发光光谱对具有相似化学成分的 ZnO 基薄膜和粉末的晶体结构进行了比较研究。不同涂层参数(化学成分、厚度)对薄膜和粉末的光谱和形态特性的影响揭示了形成 ZnO 纳米晶体与玻璃表面之间相互作用的结构特征。ZnO-SnO2 涂层和粉末是通过液态聚合物盐技术制备的。该方法在成核和形成氧化物晶体的初始生长阶段期间提供了涂层前体与玻璃表面之间的紧密接触。纳米晶体和衬底表面的相互作用是 ZnO 薄膜中纹理形成的原因,并决定了它们的一些光学特性。
