Photoluminescence Emission and Raman Vibration Properties of Asymmetric Nanoparticle ZnO Doped Mn2+ Fabricated by a Solvothermal Method

Abstract

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.
