The nanoparticles of Zn doped β-Ga2O3 were synthesized by sol-gel combustion method and their structural and optical properties were investigated. The formation of ZnGa2O4-β-Ga2O3 heterostructure by the doping of Zn ions was not affected the absorption and emission band centers, but the replacement of Ga3+ ions by the small amount of Zn2+ reduced the band gap of β-Ga2O3. The defects (O and Ga vacancies) created in the β-Ga2O3 nanoparticles by the doping of Zn2+ ions, which is having lesser oxidation state than that of Ga3+ ions, enhanced the intensity of green emission.
