Colloidal synthesis and characterization of nanostructured pure ZnO and In doped ZnO thin films

Article scientifique 2022 Anglais

Résumé

Abstract In this study, we report the effects of concentrations of the Indium doping (from 0 to 10wt%) on the structural, morphological, and optical properties of Indium doped ZnO thin films prepared by the colloidal method and deposited with the dip coating technique on glass substrates. X-ray diffraction (XRD) analysis indicates that the all pure and doped ZnO thin films have a polycrystalline nature with a hexagonal wurtzite phase. XRD results demonstrate that the particle size of ZnO varied with the concentrations of the Indium doping. Raman scattering spectra confirmed the wurtzite phase and the presence of intrinsic defects in our samples. UV–Vis spectrometer measurements show that all the pure anddoped ZnO thin films are highly transparent in the visible wavelength region (≥ 85%).The photoluminescence (PL) spectra of the thin films exhibit defects related visible emission peaks, with intensities differing owing to different concentrations of zinc vacancies.
