Abstract

The aim of this work to study the effect of the thermal annealing at(100, 150 and 200°C) on the optical properties of Ag O thin films. The samples were prepared on glass slides by chemical spray pyrolysis at 50°C.The optical characteristics such as absorption coefficient, optical energy gap, extinction coefficient and refractive index were investigated by UV/V spectrophotometer in the wavelength range (380 – 500)nm. From reults show that the optical energy (Eg) values was decreased from (2.574) eV to (2.558) eV when the thermal annealed degree decreased from (200°C) to (100°C). Whereas the maximum value of the refractive index (n) for all thin films were given about (2.164). Also the extinction coefficient (K) and the real and imaginary dielectric constants. The results indicate the films have good characteristics for optoelectronic applications.
