In this study, ZnO doped Mn2+ 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 were investigated by X-ray diffractometry, Raman spectroscopy and transmission electron microscopy. The photoluminescence (PL) was measured at room temperature showed red-shift of near-band-to-band emission and the evolution of visible emissions in the doped samples. This work analyzed the PL characteristics of synthesized samples and revealed the role of the dopant Mn2+ on defect states of ZnO.
