Synthesis and characterization of ZnGa2O4 particles prepared by solid state reaction

► Synthesis of ZnGa2O4 particles produced from metallic Zn and Ga particles. ► The structural comparison of spinel and partially inverse spinel structure in ZnGa2O4. ► The Ga atoms occupied 13% of tetrahedral site in ZnGa2O4. ► The band gap, calculated from climate point of UV-visible, was found as 4.6 ± 0.1 eV. ► The optical analyses were shown defective ZnO structure in ZnGa2O4.
