Abstract :
In this study, the doping impact of indium (In) on the actual properties
of CdO at different content of (1, 2, and 3 wt% In) was discussed.
The samples were prepared utilizing the spray pyrolysis method. The
structural, topographical, and optical properties were characterized X-ray
diffraction (XRD) analysis, UV-Vis, and atomic force microscope (AFM).
The surface topography was discussed by utilizing AFM analysis. Results
display that the average diameter appears to be dependent on the indium
content. The particle size was decreased from 78.05 to 65.77 nm when In
content was increased from 0% to 3%. It is found that the roughness of
the film was decreased to 3.03 nm via increasing In content to 3%. Also,
the band gap of prepared samples were studied and compared. Results
revealed that the value of band gap is decreasing via doping indium. The
band gap of bare CdO, 1%In-CdO, and 3%In-CdO were determined 2.63,
2.54, and 2.46 respectively.
