Resonance modulated amplified emission from CdSSe nanoribbons

We present evidence of amplified emission mediated by surface plasmon polaritons (SPPs) from a CdS(0.2)Se(0.8) nanoribbon (NR) supported on a gold-coated silicon substrate. Room temperature amplified emission is observed from the nanoribbon above excitation irradiances ~25 W/cm(2) when it is support...

description We present evidence of amplified emission mediated by surface plasmon polaritons (SPPs) from a CdS(0.2)Se(0.8) nanoribbon (NR) supported on a gold-coated silicon substrate. Room temperature amplified emission is observed from the nanoribbon above excitation irradiances ~25 W/cm(2) when it is supported on the gold coated silicon substrate. The nanoribbon is shown to act as a resonator cavity, leading to amplification of discrete wavelengths in the emission spectrum. Evidence for the formation of SPP waves between the gold-coated substrate and the nanoribbon is shown, and the resulting wavenumber increase allows for the matching of theoretical resonance wavelengths with those observed experimentally.
