Full TextAbstract
Abstract: Pure ZnO and Zn1-xMnxO (x=0.02 and 0.06) nanopowders have been synthesized by sol–gel technique at low temperatures. XRD results indicated that the crystal structure is hexagonal and there is no secondary phase. The compositional characterization of Mn-doped samples was investigated by EDX spectra. The size and morphology of nanoparticles were obtained by SEM and TEM images. Optical constants such as refractive index and extinction coefficient were evaluated from transmittance spectrum in UV region. The optical band gap energy showed a red-shift from 3.22 eV to 3.14 eV for pure and Zn0.94Mn0.06O, respectively. The Curie temperature of Mn-doped ZnO samples were determined and at room temperature no ferromagnetism state was observed.
