Abstract
The defect creation on the surface of the metal oxide structure by infrared laser irradiation played a vital role in enhancing its optical properties. Herein, Zn/ZnO thin film was synthesized by pulsed laser deposition of Zn metal, followed by creating oxygen vacant by infrared laser irradiation, then the Ag layer was used to coat the irradiated ZnO thin film by pulsed laser deposition of Ag metal to produce Ag/ir-Zn/ZnO nanocomposite structure. The effect of creating vacancies on the thin films of ZnO has appeared on the optical and structural properties of Ag/ir-Zn/ZnO thin film was studied by X-ray diffraction, X-ray photoelectron spectrometer, and energy dispersive X-ray diffraction. The response of nonlinearity of Ag/ir-Zn/ZnO thin film was enhanced in compared with that of thin films of a single layer of CdO, single layer Ag, or CdO/Ag thin film.Graphic abstract
