Stimulated emission behaviors from excitons in CdS nanoribbons

Abstract

Semiconductor nanowire show promising properties in nanoelectronic and nanophotonic devices. The nearfield photoluminescence spectra of CdS nanoribbon indicated the luminescent light waveguide behavior. The stimulated emission from the two-phonon bound excitons was also observed at room temperature in this nanoribbon with intense ns laser pumping. © 2006 IOP Publishing Ltd.
