Abstract
In the present study, a gold/nickel oxide (Au/NiO) nanoalloy was generated by irradiating two nano-metallic material solutions using a green laser. The produced Au/NiO nanocomposites were characterized by UV–Vis–NIR spectroscopy, an X-ray diffraction pattern, TEM and SEM imaging, and photoluminescence and DLS tests. Depending on the concentration of Au NPs in the suspension medium, the final characteristics of Au/NiO nanocomposites vary significantly. Au NPs exhibit an extremely high plasmonic absorption peak at approximately 530 nm. They melted by absorbing the energy of the second harmonic of the laser beam, forming an Au/NiO nanocomposite. Additionally, our results demonstrated that after irradiation with a green laser, the bandgap energy of samples was reduced to 5, 4.3, and 4 eV as the number of Au NPs in nanocomposite structures increased, indicating that the addition of gold to nickel oxide NPs improves their conductivity and reduces the bandgap energy of samples. Moreover, due to composition formation, the number and size of Au NPs dropped following green laser irradiation, while NiO NPs grew in size. This work created an AuNiO nanocomposite by laser ablation, which is a highly effective approach for fabricating nanostructures.
