Abstract

In this study, Mn2+-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 Mn2+ to defect states of ZnO.

Keywords: Mn ion, ZnO, solvothermal synthesis, nanoparticle, photoluminescence
