One-Step Hydrothemal Synthesis of Nitrogen Doped β-Ga₂O₃ Nanostructure and Its Optical Properties

Nitrogen doped β-Ga2O3 nanostructures were synthesized using a simple one-step aqueous approach. The structure and morphology of the nanostructures were characterized. Both the GaOOH precursor and β-Ga2O3 nanostructures showed the rod-like morphology. Meanwhile, the β-Ga2O3 nanostructures were doped with nitrogen, which was proved by X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) and cathodoluminescence (CL). The results showed nitrogen-doped one-dimensional β-Ga2O3 nanostructures were achieved by in situ doping while maintaining the morphology. Meanwhile, as a straightforward method, the excellent luminescence properties are suitable for application in white-LED phosphors and novel optoelectronic devices.
