This paper studies the effect of plasmon AgNPs on the spectral properties of semiconductor CdTe QDs. The size and shape of the prepared nano-materials have been characterized using transmission electron microscope. CdTe luminescence enhancement has been reported to be 11 fold. Red shift and decrease in the emission threshold have been reported. Förster resonance energy transfer (FRET) between CdTe QDs at nanoscale proximity to AgNPs was calculated. The effect of AgNPs on fluorescence life time of CdTe QDs was also measured. These nanocomposites are promising candidates for LED and laser devices.

Abstract
This paper studies the effect of plasmon AgNPs on the spectral properties of semiconductor CdTe QDs. The size and shape of the prepared nano-materials have been characterized using transmission electron microscope. CdTe luminescence enhancement has been reported to be 11 fold. Red shift and decrease in the emission threshold have been reported. Förster resonance energy transfer (FRET) between CdTe QDs at nanoscale proximity to AgNPs was calculated. The effect of AgNPs on fluorescence life time of CdTe QDs was also measured. These nanocomposites are promising candidates for LED and laser devices.File in questo prodotto:
