Abstract
In this research deposition of thin films of zinc Stanat alloys (Zn2SnO4) zinc stannate using the method of thermal spray (Spray-Pyrolysis Deposition) (SPD) on slices of quartz using zinc acetate (zinc acetate) Zn (CH3COO) 2.2H2O and tin chloride SnCl2 .2H2O (tin chloride) at different mixing ratios (3: 1), (2: 1), (1: 1) (Zn: Sn) and at different concentrations Molar (0.1-0.3-0.5-0.7-0.9-1.1M), studied the structural and optical properties of the films by using x-ray diffraction XRD device and spectrophotometer, show that the prepared films at the mixing ratio (2:1) Zn: Sn and molar consentration (o.9) M is the best in terms of their characteristics structural reaching Crystaline Size approximately 15nm. The porosity of the films prepared calculation shows that the porosity associated particle size is proportional, and thermal annealing of films prepared operation mixtures Zn2SnO4 at temperatures (660-700-8000C) and found that the structural and optical properties influenced by annealing temperature, as shown the study improvement in the crystalline structure of the films and growing Crystaline Size and porosity increased degree of annealing temperature and this simeller with some reference works, by using an atomic force microscope (AFM) studied the topography of surfaces prepared and annealed films at different temperatures and the study of the effect of thermal annealing process on the topography of surfaces movies where It shows that the square root of the mean square roughness and surface roughness values increase with annealing process.
