In this paper, Ga-doped ZnO nanoparticles (GZO NPs) are synthesized by the solvothermal method from different precursors and with different Ga doping concentrations (0%, 1%, 3%, 5%, 7% and 9%) at the same temperature of 250 °C in the oleylamine solvent. | Synthesis of Ga-doped ZnO nanoparticles by solvothermal method
