Influence of Doping on the Structural, Optical Properties and Dispersion Parameters of CdO Thin Films
Journal Title: International Journal of Modern Research In Engineering & Management. - Year 2019, Vol 2, Issue 6
Abstract
Un-doped and bismuth (Bi) doped cadmium oxide (CdO) films were deposited on glass substrates by chemical spray pyrolysis method at (400℃) temperature. The effect of Bi concentration (1,3 and 5 wt %) on the structural, optical properties and dispersion parameters of CdO thin films were investigated. X-ray diffraction patterns indicated that the all films had a polycrystalline with cubic structure and crystallite size increases with the increase of doping percentage. The optical properties and dispersion parameters of films have been studied over a wavelength range (400-900) nm. The optical band gap, refractive index, single-oscillator energy, dispersion energy, moments of the optical spectra (M−1) and (M−3), average oscillator strength, average oscillator wavelength were calculated and analyzed as a function of Bi concentration. It was shown that the doping percentage has significant effect on the properties of CdO thin films.
