Effect Of Solution Molar Concentration On Cdo Thin Films Prepared By Simplified Spray Pyrolysis Method

CdO thin films were deposited by perfume atomizer spray pyrolysis method on glass substrate at 2000 C by varying solution molar concentration such as 0.1 M and 0.2 M. X – ray diffraction (XRD) analysis show that the prepared cadmium oxide thin films belongs to cubic structure with preferential orientation along with (111) direction. The thickness of the films was determined by Stylus profiler. The average optical transmittance of the CdO films in the range of 300 – 800 nm, is about 60%. Estimated band gap energy (Eg) is 2.234 eV and 2.30 eV for 0.1 M and 0.2 M film respectively. Photoluminescence (PL) spectra showed a strong emission peak around 523 nm.
