Synthesis and characterization of monodispersed β-Ga₂O₃ nanospheres via morphology controlled Ga₄(OH)₁₀SO₄ precursors.

To our best knowledge, monodispersed β-Ga2O3 nanospheres were successfully synthesized for first time via morphology-controlled gallium precursors using the forced hydrolysis method, followed by thermal calcination processes. The morphology and particle sizes of the gallium precursors were strongly dependent on the varying (R = SO4(2-)/NO3(-)) concentration ratios. As R decreased, the size of the prepared gallium precursors decreased and morphology was altered from sphere to rod.
