Full TextAbstract
Abstract: Zn ˺-xMnxO (x= ˹, ˹̄˹˻, ˹̄˹˿, ˹̄˺˹, ˹̄˺˾) nanopowders were synthesized by the sol gel technique calcinated at low temperatures. The solubility of magnetic impurity has been increased and no detectable secondary phases were observed even in the high Mndoping samples. The phase formation, size and morphology of nanoparticles were investigated using Xray diffraction, TEM and SEM observations. Optical characterizations, the effect of doping and lattice dynamical parameters were carried out by means of Fourier transform infrared (FTIR) spectroscopy. The optical band gap energy decreases from ˼̄˻˻eV to ˼̄˺˻eV for pure ZnO and Zn ˹̄̂Mn ˹̄˺O dispersed powders, respectively.
