Single crystalline CdS (hexagonal) nanobelts have been synthesized using thermal evaporation at temperatures ranged from 1000 to 1200°C. These nanobelts universally grow along the [120] direction. The nanobelts fabricated at 1000°C appear to be much more uniform than those at 1200°C. Moreover, the surface of the nanobelts grown at 1200°C is very rough compared to the former. Such roughness is due to the secondary growth of CdS crystallites on the nanobelts' surfaces. Cathodoluminescence studies of the two samples demonstrate mainly green emission in the sample grown at 1000°C, but red emission in the other one. The growth mechanisms of the nanobelts and the luminescence differences of the two samples are discussed.
