Synthesis and Structural Characterization of Transition metal doped MgO: Mg0.95Mn_(0.01)TM_(0.04)O (TM= Co, Ni, Cu)

摘要

In the present work, preparation and characterization of transition metal doped MgO: Zn_(0.94)Mn_(0.01)TM_(0.05)O (TM =Co, Ni and Cu) nano-particles have been reported. Transition metal doped samples of MgO were synthesized by Sol gel auto combustion method. Structural characterisation from XRD and SEM show the formation of single-phase primary particles, nearly of spherical shaped nano-crystallites. The crystallite size was found to be 78.2,67.02,78.11 and 64nm for pure, Co, Cu and Ni doped MgMnO nano-particles, respectively. Hence, the average crystallite size increases monotonously from Co to Cu doping.
