Abstract
|
|
|
|
The thin films of TiO2-x, were prepared by vapor oxidation and TiO2 single crystal was reduced by heating in argon atmosphere. The photo-electrochemical properties of these samples were studied. When the photocurrent was scanned in 1M NaOH electrolyte solution, several peaks were observed in the vicinity of 320nm in the UV-region and in the vicinity of 520nm, 620nm, and 740nm in the visible-region. Contrary to the previous suppositions, those peaks were produced by the second-order lines from the grating monochromator.
