| We synthesized the uniform monoclinic gallium oxide (Ga2O3) nanobelts by a simple thermal annealing of GaN powders. The as-syn-thesized nanobelts were rectangular in cross-sectional shape with width ranging from 100 to 700 nm. The length direction of the nanobelt was along [010]. Photoluminescence measurement under excitation at 325 nm showed that the Ga2O3 nanobelts had a blue emission at around 454 nm. |
