Influence of annealing temperature on properties of nanocrystalline CdO thin films synthesized via thermal oxidation process

Chemical bath deposited CdS thin films have been annealed in air at different temperatures to obtain CdO films via thermal oxidation route. The obtained nanostructured and highly transparent thin films of CdO have wide range of applications in solar cells, smart windows, optoelectronic devices, gas sensors; etc.The influences of annealing temperature on structural, morphological, optical and solid state properties of prepared CdO films have been investigated. The techniques used for the investigation includes x-ray diffractometry, scanning electron microscopy, UV-VIS spectroscopy. The optical energy band gap and other optical constants were evaluated
