Abstract
ABSTRACT Cobalt doped Magnesiun Oxide nanofilms were grown by electrodeposition method using heptahydrated Magnesium tetraoxosulphate VI salt as source of Magnesium ion Citric acid as oxidizing agent. Hexahydrated Cobalt Chloride salt was used as source of Cobalt ion and Sodium hydroxide as pH adjuster. The percentage doping was varied from 3 to 23 in intervals of 5. Results of the study show that the optical properties viz absorbance reflectance refractive index extinction coefficient electrical conductivity complex dielectric constant and optical conductivity are directly proportional to percentage doping with cobalt while transmittance is inversely proportional. The film exhibits low absorbance reflectance and high transmittance in all the regions of electromagnetic spectrum.
