Effect of annealing temperature on the structural, optical and topographical properties of cadmium oxide (CdO) nanoparticles
Keywords:thin films, cadmium oxide, chemical bath (CBD), Changing annealing temperatures
Cadmium oxide (CdO) Nano film was prepared by chemical bath (CBD) technique, with concentration (0.03 M), volume (150 ml) and settling time (24 h). It was annealed to different temperatures ranging from (RT = 300 , 350 , 400 Cº) for a period of three hours. The effect of changing annealing temperatures on the structural, optical and surface topographical properties was studied using X-ray, AFM, Uv and SEM. The prepared film was examined using scanning electron microscopy (SEM) technology with a magnification of (2,000 x) for the purpose of identifying the nature of the prepared film surface and observing the change in particle size with increasing annealing temperatures after sedimentation. It was found that the average particle size is 32.51 nm, the preferential orientation along the surface (200) and the TC parameter is 1.8 for the prepared film. As for the TC of the annealed films, it corresponds to the annealing temperatures which are (1.8, 1.645, 1.764, 1.79).
And the corresponding particle size (57, 58, 51 and 51), according to the stress change with the denaturation temperature, was within the range 0.157-0.376 GPa.
On the other hand, the results of the energy gap showed that the prepared membrane measured by Nano dimensions and the presence of the phenomenon of quantum effect.
