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...
