In the present work, the influence of annealing on structure, electron spin resonance (ESR), and Raman scattering (RS) spectra of x at.% Mn-doped ZnO (x=4 and 8) ceramic compounds has been systematically investigated. The samples were annealed at temperatures (Tan) between 400 and 1000C for 12 h. The obtained results revealed the strong dependence of x-ray diffraction, ESR, and RS spectra on the annealing temperature Tan) . Mn2+ ions did not substitute into Zn2+ sites in samples annealed in the range of 400-600C but started to substitute into Zn2+ sites for annealing temperatures Tan >600C. The results of this investigation provide further insights into the physical processes occurring in Mn-doped ZnO materials due to annealing.
