ABSTRACT

Abstract: Cobalt doped Cadmium Cobalt Oxide nanofilms were deposited by electrodeposition method using hexahydrated Cobalt Chloride salt as source of Cobalt ion, hydrated Cadmium Chloride salt as source of Cadmium ion, Citric acid as oxidizing agent, and Sodium hydroxide as pH adjuster. The deposition voltage was varied from 8.5V to 14.5V in intervals of 1.5V. Results of the work show that the optical properties viz; absorbance, reflectance, and refractive index are directly proportional to the deposition voltage while transmittance is inversely proportional. The film exhibits high transmittance in all the regions of electromagnetic spectrum but low absorbance and reflectance in the regions. It is a wide bandgap semiconductor
