Preparation and Optical Property of Mn-Doped ZnO Nanorods

Abstract:

Mn-doped ZnO (Zn_0.97Mn_0.03O) nanorods were synthesized by sol-gel method combined with subsequent heat treatment. The structure and optical property of Mn-doped ZnO nanorods were studied by x-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), and fluorescence. The results of electron microscopes illuminate that the Zn_0.97Mn_0.03O nanorods are prepared at calcinations of 450 under the protection of nitrogen. The Zn_0.97Mn_0.03O nanorods are composed of small particles of size 20–30 nm. Fluorescence spectra of Zn_0.97Mn_0.03O nanorods exhibit that there are two very strong blue emission peaks at 451 nm and 461nm except a strong UV emission at 396 nm.
