A method to directly synthesize single crystalline CdS nanobelts has been developed. The advantages of the method in rapid synthesis within several minutes and catalyst free comparing to the previous method propose a potential avenue to the further practical device production and applications. The as-synthesized CdS nanobelts grow along the [100] crystalline direction with usually 500-2000 nm in width and about tens to several hundred micrometers in length. Two luminescence peaks around 516 and 758 nm in room-temperature photoluminescence spectrum are ascribed to the band-to-band and trap emission, respectively.
