Abstract:

In this study, the pH effect of CdO thin films, extended by SILAR technology on the glass underground at room temperature, was studied. The structural, morphological and optical characteristics of the obtained fine films were studied by taking X-ray diffraction (XRD), scanned electron microscope (SEM) and UV vis spectrum meters respectively. The XRD results showed that thin films showed direction to different angles and plates at pH 11.5 or higher values. SEM images showed that the film's surface morphology changed significantly with the pH change. Optical cooling measurements showed that the band range increased due to the rise in pH.

Abstract:

In this study, pH effect was investigated on CdO thin films which were grown by SILAR technique on glass substrates room temperature. X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV vis spectrophotometer measurements were examined for structural, morphological and optical properties of thin films. The XRD results showed that thin films exhibited orientation at different angles and planes at pH 11.5 and higher. SEM images showed significant changes in the surface morphology of the films with the change of pH value. The optical absorption measurements showed that the band gap was increased due to the pH increase.
