Abstract:
?-Ga 2O 3 one-dimensional (1D) nanostructures including nanowires, nanoribbons and nanosheets were synthesized via a combined carbon thermal reduction and chemical vapor deposition (CVD) approach. All of these nanostructures consist of single-crystalline monoclinic structure, which has been confirmed via high-resolution TEM and electron diffraction analysis. We obtained ?-Ga 2O 3 nanowires at high temperature zone, nanosheets, and nanoribbons at medium temperature zone at low-pressure environments. We found that ?-Ga 2O 3 nanowires and nanoribbons have diversified different growth directions. The optical properties of ?-Ga 2O 3 nanowires and nanoribbons from UV-vis spectra show that the bandgaps are red-shifted by 0.13 eV
