Abstract

•Nanocomposite oxide Ag2O·CeO2·ZnO has been prepared.•Characterized by XRD, SEM, EDS and PL spectra.•Low temperature solid state PL spectra observed.•NBE, blue, green, orange and red emissions are observed.•Excellent photocatalytic and anti-bacterial activities observed.

A novel multi-metal nanocomposite oxide Ag2O·CeO2·ZnO has been prepared by co-precipitation of their carbonates from aqueous solutions of the metal nitrates following calcinations and annealing 5 h at 450 °C and 4 h at 600 °C. Ag2O·CeO2·ZnO has been characterized by XRD, SEM, EDS and PL spectra. According to XRD results the crystallite size of Ag2O·CeO2·ZnO varies in the range of 19–111 nm with an average size of 50 nm, which is in good agreement with SEM results. Elemental analysis was performed by SEM–EDS. Emissions of Ag2O·CeO2·ZnO has been observed in UV (NBE emission), visible and NIR regions at 325 nm excitation by a line of He–Cd laser. Photocatalytic as well as anti-bacterial activities have been studied. The nano composite Ag2O·CeO2·ZnO shows an excellent photocatalytic dye degradation activity.
