electro-optical properties of cds thin films by chemical bath technique

In this research work, cadmium sulphide thin film deposited on to glass substrate in a non-aqueous medium at 80 °c. the various physical preparative parameters and the deposition conditions, such as the deposition time and temperature, concentrations of the chemical species, ph, speed of mechanical stirring, etc., were optimized to yield good quality films. the as-prepared sample is tightly adherent to the substrate’s support, less smooth, diffusely reflecting and was analyzed for composition. the synthesized film is characterized using x- ray diffraction (xrd), electrical and optical properties. it appears that the composites are rich in cd. the grown cds thin film had an orange-red color. a band gap of cds thin film is 2.41 ev.  the average crystallite size of the cds film was 21.50 nm. the resistivity of the cds thin film is about 5.212 x 105 w cm.
