    Chemically Deposited Doped Titanate Ternary Metal Oxide Thin Films Via Spray Pyrolysis Route-Preparation, Characterization and Solar Cell Application Analysis
    (4th Africa Nano Conference and Workshop, 2021-07) Eze, C. N.; Onyia, A. I; Nnabuchi, A. I
    Spray pyrolysis method of deposition is a simple, cheap, low cost and conventional method that gives uniform deposition. With this motivation, a simple approach of spraying ZnTiO3 nanoparticles on a substrate is reported. The approach occurs with ternary metal oxide and is environmentally friendly. This follows the quest to further improve the physical and chemical properties of ternary metal oxide which has become noticeable in recent times. The crystallization temperature of ZnTiO3 was 2000C. Among other investigations the SEM result shows a perovskite structure-like morphology. Further characterization performed on the thin film for the structural aspect which gives XRD of the thin film shown on the diffractogram is in agreement with the standard diffraction of ZnTiO3 which is identified as tetragonal structure. UV-Vis absorption spectroscopy was also used to characterize the final product and the spectra indicated that the absorbance obviously increased in the visible light region with absorption peak at about 209 nm and with optical band gap which infers that it has potential application in solar energy devices.
