This research focuses on the comparative analysis of the optical properties of zinc oxide (ZnO) nanorods doped with different nanoparticles (Au, Cu, Pt, Ni, and Gr). Both undoped and doped ZnO samples were prepared using a mixing procedure under identical conditions.

X-ray diffraction pattern certain ZnO nanorods with hexagonal wurtzite structure and shown succeeded doping with (Au, Cu, Pt, Ni, and Gr) nanoparticles. Fourier Transform Infrared (FT IR), UV-visible, and photoluminescence (PL) spectroscopy were used to examine the modification in the optical properties of the samples due to the doping procedure. The results displayed considerable changes in the optical properties of ZnO nanorods after doping, including variations in emission peaks and energies of band gap, which refer to the institution of defects in structure and charge transfer processes. These results indicate that doped ZnO nanorods have scope applications in optoelectronics, biomedicine, and electronics.
