Abstract

In this study, ZnO-CdO composites were synthesized by hydrothermal
method. Two different contents of the nano-composites have been fabricated for
the investigation of structural, morphological, optical and electrical
properties. X-ray diffraction (XRD), FTIR, scanning electron microscopy (SEM),
UV-VIS-NIR spectrophotometer and two probe methods were used for these analyses.
At the same time, the chemical analysis of the sample was measured by EDX
analysis. The TG-DTA analyses were made to determine the thermal stability. The
optical band gap of composites was found to be 2.78 and 3.06 eV, respectively,
with an increase in the content of the Zn precursor.

Keywords
