Annealing Temperature Effects on the Optical Properties of CdO Thin Films Deposited by CSP Technique

Download PDF

Abstract:

By chemical spray pyrolysis method. The CdO thin film prepared at constant film thickness (350 nm). The prepared films are annealed at a temperature of 450 and 500 °C. The optical properties are calculated from the measurement of UV-Visible spectrophotometer spectrum in the range of (300-900) nm at room temperature. The transmittance, absorption coefficient, extinction coefficient, refractive index, and skin depth are calculated as annealing temperature. The energy gap decreased from 2.52 eV to 2.47 eV when the annealing temperature increased from room temperature to 500 °C.
