Preparation of CaTiO3 Thin Film by Sol-Gel Dipping Coating
Abstract:
Smooth and dense films of CaTiO3 were prepared on the glass substrate by a sol-gel dip coating method. Characterization of the product was carried out by different techniques such as powder X-ray diffraction (XRD), scanning electron microscope (SEM) and UV–vis optical spectroscopy. The results showed that pH and water contents had a great influence on morphology of CaTiO3 film. When water content is 0.128 mol at PH=1.56, CaTiO3 film presents an absorption in the UV region and the band gap is estimated to 3.35 ev. The results show the large potential of this material in electronic structure.
