Characterization of Spray Pyrolysed CuInS2 Thin Films
An indigenously developed chemical spray pyrolysis system was used to deposit polycrystalline CuInS2 thin films. It was found that smaller spray rate results in films with better crystallinity and lower resistivity. Increase in surface roughness of the films was observed for higher spray rates. Variations in film stoichiometry with composition of spray solution were analyzed along with its opto...
متن کاملFabrication, characterization and investigation of gas sensing properties of MoO3 thin films
In this research, molybdenum oxide (α-MoO3) thin films were coated on glass substrates using spray pyrolysis technique. 0.05 M ammonium heptamolybdate tetrahydrate was used as precursor and deionized water as solvent. The effects of carrier gas pressure, during the spraying of the solution, on the structural, optical, morphological and gas sensing properties of thin films were studied. X-ray di...
متن کاملPREPARATION OF MoO3 THIN FILMS BY SPRAY PYROLYSIS AND ITS GAS SENSING PERFORMANCE
MoO3 thin films have been prepared by a simple spray pyrolysis technique at substrate temperature 250C. The structure and morphology of thin films are characterized by X-ray powder diffraction (XRD), scanning electron microscopy and UV-vis spectroscopy. The gas sensing properties of MoO3 thin film is studied at gas concentration 400 ppm and working temperature of 100–400 C. It was found that th...
متن کاملSYNTHESIS, CHARACTERIZATION AND GAS SENSING PERFORMANCE OF SOL-GEL PREPARED NANOCRYSTALLINE SnO2 THIN FILMS
Nanocrystalline SnO2 thin films were successfully prepared using sol-gel dip coating technique. The starting precursor was used as tin chloride dihydrate (SnCl2.2H2O), ethanol and glycerin. As the prepared films were fired at 500 o C. These films were characterized using XRD, FESEM and TEM to known crystal structure, surface morphology and microstructure property. Elemental composition was stud...
