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. FoĢrster 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.
