      abstract     = {ZnO and Zn$_{0.998}$Mn$_{0.002}$O ceramics were made by
                      sintering in air at 1150 °C for 3 h. Two types of doped
                      samples – furnace cooled and quenched from the sintering
                      temperature in air – were prepared. Raman scattering,
                      UV-vis optical absorption, photoluminescence and electron
                      paramagnetic resonance (EPR) study of obtained ceramics
                      testify to the formation of Mn$_{Zn}^{2+}$ centers upon Mn
                      doping, and the EPR spectra confirmed the effect of cooling
                      rate on their number. In accordance with available
                      literature data, three Raman modes at about 480, 530 and 580
                      cm$^{−1}$ were revealed in Raman spectra of doped ceramics
                      in addition to those of undoped ones. Based on the analysis
                      of obtained and reported earlier experimental data, the
                      conclusion has been made that the appearance of these
                      additional Raman modes in ZnO:Mn materials is caused by the
                      photoionization of Mn$_{Zn}^{2+}$ centers and the
                      interaction of photoelectrons with phonons.},
