Abstract

MgxZn1-xO particles were synthesized by the sol-gel technique using acetate of zinc and magnesium in a homogeneous aqueous reaction medium. XRD showed that the particles possessed a polycrystalline hexagonal wurtzite structure. The transmission spectroscopes of ZnO, MgxZn 1-xO and the mixture of ZnO with MgO were investigated. It was found that the band gap of zinc oxide was increased from 3.32 to 3.65 eV by doping 15% magnesium oxide. TEM picture revealed that MgxZn1-xO particle was about 30 nm with a narrow size distribution. The conductivity and the dielectric properties of the powders have also been improved by Mg doping.
