| Abstract | Molybdenum oxide thin films were prepd. electrochem. onto the selenium predeposited tin oxide-coated glass substrates using 0.22 M sodium citrate (C6H5Na3O7) soln. (pH 8.3) and sodium molybdate as a precursor. Cyclic voltammetry was used to det. the deposition potential effects on molybdenum compd. speciation, while quant. thin film compn. was obtained from XPS depth profiles. Thin molybdenum film growth and compn. was potential dependant. Predominant molybdenum species was Mo(IV) at all deposition potentials and deposition times. Optical properties of the molybdenum oxide thin films were detd. using UV-VIS spectroscopy. The absorption edge varied between 560 and 650 nm, whereas optical band gap values-between 1.79 and 2.19 eV-well within the limits for solar light-induced chem. reactions. [on SciFinder(R)] |
