REFINEMENT ANALYSIS, PHOTOLUMINESCENCE AND MAGNETIC PROPERTIES OF Zn1-XMnXO (x = 0.00, 0.01, 0.02, 0.03 & 0.04) NANOPARTICLES SYNTHESIZED BY COMBUSTION TECHNIQUE

Zn1-XMnXO (x = 0.0, 0.01, 0.02, 0.03 & 0.04) nanoparticles were fabricated through a simple combustion method and their structural, morphological, chemical, optical, photoluminescence and magnetic properties were systematically analyzed. X-ray diffraction (XRD) and Rietveld refinement (RR) analysis studies divulged that, the synthesized nanoparticles exhibited the hexagonal structure without any impurity phase. Morphology studies revealed that the synthesized nanoparticles were nearly spherical in shape with uniform size distribution. A clear Blue shift was recognized in the ZnO nanoparticles when doped with Mn ions. The photoluminescence (PL) spectra of all the synthesized nanoparticles exhibited the same emissions and PL intensity diminished with increase in Mn doping concentration. All the synthesized nanoparticles exhibited room temperature ferromagnetism (RTFM) and Zn1-XMnXO(x=0.02) nanoparticles displayed better ferromagnetic property than other compositions. The captivate properties of the ZnO: Mn nanoparticles may more useful for optoelectronic and spintronic applications.
