CdZnTe:In (CZT:In) films were deposited on fluorine-doped tin oxide-coated (FTO) substrates by close-spaced sublimation method, and the structural, morphological, and optical properties of CZT:In films with different thicknesses were studied in detail. Working as a photoanode, the photoelectrochemical (PEC) properties of CZT:In films were investigated, which indicated that the photocurrents of CZT:In films were first increased and then decreased with the increase of film thicknesses under the same bias voltage. Annealing process improved the stability of the CZT:In photoanode. The fabrication of FTO/CZT:In/Pt and FTO/CZT:In/TiO2/Pt photoelectrodes enhanced the PEC properties of CZT:In films and achieved photocurrents of up to 4.2 and 8.2 mA/cm2, respectively.

A method is reported in which visual observation of the incandescent filament by means of commercially available television equipment is combined with temperature measurements along the coil. The features of an installation, consisting of a 'Plumbicon' camera tube, monitor and video-tape recorder in conjunction with a quotient pyrometer measuring the radiation intensity at two wavelengths, are described. Some examples of experimental results obtained with various types of tungsten halogen lamps are illustrated by photographs taken from the television monitor screen and by temperature recordings. Though still pictures can give only a faint idea of the information value of video-tape recordings the reported method is a valuable tool for investigating the dynamic processes occurring in the filament under various burning conditions.
