Abstract This study deals with the synthesis of some physical properties of (CdO/NiO) nanocomposite via Sol-Gel method and their antibacterial activities. The NiO and CdO nanoxides as well as the CdO/NiO oxide mixture were prepared in five samples with different concentrations where the ratio of CdO/NiO was [(1: 0), (3: 1), (1: 1), (1: 3), (0: 1)], by using the gel solution by means of a polyvinyl alcohol solution ( PVA ). The samples were platelimb at (500̊C) for three hours. The structural properties of the prepared oxides resulting from the cracking process were studied. The XRD results showed the presence of pure cadmium oxide diffraction patterns in the sample (S 1 ) as well as pure nickel oxide in the sample (S 5 ), and confirmed the presence of the CdO / NiO oxide mixture in the samples (S 2 , S 3 , S 4 ). The results of XRD also showed, through calculations, that the specific surface area increased with increasing granular size and decreased with decreasing granular size. XRD calculations also showed that the intensity of eruptions decreased as the granular volume increased and, inversely, increased with decreasing granular size.

In this work, pure Zinc oxide and tin doped Zinc oxide thin films nanoparticles with various volume concentrations of 2, 4, 6, and 8V/V% were prepared by using the sol-gel method. The optical properties were investigated by using UV-Visible spectroscope, and the value exhibits the direct allowed transition. The average of transmittance was around ~(17-23) %in visible region. The optical energy band gap was calculated with wavelength (300-900) nm for pure ZnO and Sn doped ZnO thin films which decreases with increasing concentration from 3.4 eV to 3.1 eV respectively and red shift. The real dielectric(εr) and the imaginary dielectric εiare the same behavior of the refractive index(n) the extinction coefficient (k) respectively. The optical limiting properties were studied by using an SDL laser with a wavelength of 235 nm. ZnO and doping thin films an found efficient as optic limiting and depend on the concentration of the all samples.
