This research examines the effect of annealing temperature on the phase, optical, and structural characteristics of ZnO nanopowder. Characterization of samples was carried out using a combination of Raman spectroscopy, scanning electron microscopy (SEM), UV-visible spectroscopy, and X-ray diffraction (XRD) methods. The degrees of amorphousness and crystallinity were determined using the Search Match 3 software. The Raman spectroscopy method revealed significant changes in the shape, orientation, and distribution of ZnO nanopowder peaks formed with increasing annealing (heating) temperature, as well as explaining the phonon oscillation mode. The obtained high intensity of Raman scattering confirmed the highfrequency phonon mode of hexagonal wurtzite ZnO. The structural images of the sample were obtained by scanning electron microscopy.
