Structural and Optical Properties of (CdO)1-x(SnO2)x Thin Films Prepared by Pulsed Laser Deposition

Full Text PDF

Abstract:

CdO thin films have been deposited at different concentration of SnO2 (x= (0.0, 0.05, 0.1, 0.15 and 0.2)) Wt. % onto glass substrates by pulsed laser deposition technique (PLD) using Nd-YAG laser with λ=1064nm, energy=600mJ and number of shots=500. X-ray diffraction (XRD) results reveal that the deposited (CdO)1-x(SnO2)x thin films cubic structure and the grain size increase with increasing annealing temperature and increasing concentration of SnO2. The optical transition in the (CdO)1-x(SnO2)x thin films are observed to be allowed direct transition. The value of the optical energy gap decreases with increasing of annealing temperatures and increase with increasing concentration of SnO2 for all samples.
