Study the Optical and Structural Properties for Nano CdO Prepared by Plasma - Get Technique

Abstract

In the present study, nanoparticles of cadmium oxide have been prepared from bulk structures by the induced plasma technique at different bombardment times. These nanoparticles were prepared as thin layers on glass substrates with different thicknesses (prepared at different times of shelling). After that, they were analyzed with a UV-visible spectrophotometer, scanning electron microscope (SEM), atomic force microscope (AFM), and X-ray spectrum. When the optical properties and their constants were measured, the energy gap of the films increased in the range of 2.94–3.2 eV with bombardment times. The examining images of AFM and SEM show a clear variation in the structure, where the roughness varies with bombardment time due to the variation in the nanoparticles' diameter. Finally, the x-ray spectrum shows that the layers are completely crystalline.
