Color-tunable photoluminescence of alloyed CdS(x)Se(1-x) nanobelts.
High-quality CdSxSe1-x nanobelts of variable composition (0 </= x </= 1) were fabricated by a simple one-step thermal evaporation route. Photoluminescence measurements showed that all the CdSxSe1-x nanobelts have a single near-bandedge emission band, and their spectral maximum positions can be tuned from approximately 508 nm (for pure CdS) to approximately 705 nm (for pure CdSe). These kinds of nanobelts may have potential applications in adjustable nano/micro photoelectric devices in the visible region.
