Abstract
- Monoclinic structured β-Ga2O3 nanobelts have been synthesized through a simple thermochemical route at low temperature in range of 400–500 °C. Each nanobelt has a uniform width of about several hundred nanometers and a thickness of about 10 nm along its entire length. Micro-Raman spectrum of the β-Ga2O3 nanobelts shows that the four weak Raman bands at 112, 146, 170, and 266 cm-1 which seem to correspond to infrared (IR)-active transverse optical (TO) Au mode and/or longitudinal optical (LO) Bu mode, respectively. The IR-active bands in the Raman spectrum and the surface mode in the IR spectrum may relate to the nanoscale morphology of the nanobelts. [ABSTRACT FROM AUTHOR]
