Effect of microwave irradiation on optical properties of Barium Oxide thin films

Abstract Barium oxide (BaO) is a transparent conducting oxides, it was deposited on glass substrates using a chemical bath deposition which contain barium chlorid (BaCl2) and potassium hydroxide (KOH). The optical properties of the films including the transmittance and absorbance was studied and the energy gap was calculated. The optical properties of the films studied after radiation by microwaves with power range (360W) for a time range (1-3) min. the result show an increase in the film transmittance.
