PRODUCTION OF CUO AND CU COMPLEX DOPED ZNO FILMS, INVESTIGATION OF THEIR STRUCTURAL, OPTICAL AND RADIATION SHIELDING BEHAVIORS

Abstract

Structural, optical, and radiation response features of copper zinc oxide CuZnO thin films made by solgel spin coating are listed here. ZnO, Cu doped ZnO 1,3 and 5 wt , and Cu complex doped ZnO 1,3 and 5 wt were seven thin films created and then put through gamma radiation to test their abilities under different conditions. Research was about how Cu and complex addition changed ZnO thin films characteristics. X-ray diffraction XRD analysis showed notable changes in size, strain, and crystalline Cu and complex added samples as expected with better textured grains and more uniform structure.UV-Vis light detected a decrease in the ZnO film bandgap when Cu and Cu complex were added, increasing how much visible light could be taken in. Raman spectroscopy studied vibrational modes before and after irradiation; the peaks of all the peaks were seen to broaden and shift broadly, especially in the doped samples, as consistent with changing phonon coupling and defect structure. Moreover, radiation exposure caused highly minute changes in peak position and loss of intensity, testifying to the gamma-radiation sensitivity of the films.Results position CuZnO thin films at the forefront as next-generation material for optoelectronic devices, radiation sensors, and environmental monitoring systems.The current work contributes to metal-oxide semiconductor literature and aims to prove the importance of formulating low-cost and environmentally friendly synthesis processes for the application of high end materials.
