Abstract

ZnO ceramics undoped and doped with manganese are investigated. The Mn content NMn is varied from 1019 to 1021 cm−3. The photoluminescence (PL), diffuse reflection, and photoconductivity (PC) spectra are measured. The quenching of the self-activated ZnO emission and the appearance of the light absorption and PC are observed in the same spectral region (400–600 nm) under the doping. Simultaneously, a week PL band peaked at 645 nm arose and was assigned to intra-shell transitions in Mn2+Zn centers. Based on the analysis of obtained results, the quenching effect is attributed to the re-absorption of the self-activated ZnO emission by Mn ions. A scheme of electron transitions that allows an explanation of the low intensity of the Mn-related emission is proposed.
