چکیده
|
Co2o3 and co2o3(1-x):cux films have been deposited by using spray pyrolysis technique on a glass substrates. the optical properties of the cobalt oxide have been studied as a function of doping concentration with cu. changes in direct optical band gap energy of cobalt oxide films were confirmed after doping, eg increased from 1.48 and 1.95 ev for the undoped co2o3 to 1.55 and 2.05 ev with increasing the doping concentration to 5%. the effect of doping on the optical parameters of co2o3 thin films such as transmittance, reflectance, absorption coefficient, refractive index, extinction coefficient, and real and imaginary parts of dielectric constant has been reported.
