Abstract

Polycrystalline SrTiO3 is synthesized from a stoichiometric combination of metallic oxides by standard ceramic synthesis methods. SrTiO3 thin film X-ray diffraction examination confirmed the cubic structure phase. Strontium Titanate was deposited on the glass substrate. Studying the effect of annealing temperature on the structural properties of the glass of substrate, it is clear that increasing the annealing temperature can improve the crystallinity of SrTiO3 thin films. The surface morphology of the deposited thin films was studied using Scanning Electronic macroscopy; it is observed that the grain size increases with increasing the annealing temperature. The transitions of SrTiO3 films show high transmittance within the wavelength range (300-800nm), making them suitable for antireflection coating in this region. The optical energy gap of SrTiO3 films at various annealing temperatures was measured. It decreases as the annealing temperature of the coatings increases.
