“…The XRD patterns of doped samples were identical to the pure ZnO indicating the average crystal size of ZnO:Mn1 and ZnO:Mn3 are the same in comparison to as-prepared ZnO. We assumed that the nanoparticle of ZnO itself has an excellent doping efficiency although the dopant ion (0.083 nm in radius) is larger than the host ion Zn 2+ (0.074 nm) [12]. The morphology of ZnO nanostructured was characterized by TEM micrographs, as shown in fig.…”

In this study, Mn 2+ -Doped ZnO nanoparticle with hexagonal wurtzite phase was fabricated by a solvothermal method where various contents of Mn ion were in situ-doped in ZnO nanostructure. The crystal structure and morphological properties of the nanoparticle were investigated by X-ray diffractometry, Raman spectroscopy and transmission electron microscopy. The photoluminescence (PL) measured at room temperature showed red-shift of near-band-to-band emission and the evolution of visible emissions in the doped samples. The study also analyzed the PL characteristics of synthesized samples and revealed the role of dopant Mn 2+ to defect states of ZnO.
