摘要：

In this paper, we have reported the structural, morphological and optical studies of pure and Mn-doped ZnO nanoparticles synthesized by the simple solution combustion method. The structural, morphological and optical studies are carried out by powder XRD, FE-SEM, HR-TEM, Raman, UV-vis absorption and PL spectra. The XRD pattern indicates that the prepared particles are in hexagonal wurtzite structure with the crystalline size of around 30-60 nm. The FE-SEM and HR-TM images are coincide with each other for aggregation of particles nature. The elemental analyses of pure and doped samples are evaluated by EDX. Raman spectra of the samples show remarkable result in the polar and non-polar branches. Room temperature PL shows the near band edge related emission and the results are related several intrinsic defects in the Mn-doped ZnO nanoparticles. Blue shift of the UV emission has occurred in all the doped samples attributable to Burstein-Moss shift.
