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.
