We synthesized the uniform monoclinic gallium oxide (Ga_2O_3) 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 Ga_ 2O_3 nanobelts had a blue emission at around 454 nm.
