Abstract

In this paper the enhancement in emission from CdTe quantum dots (QDs) on Au island film as a function of CdTe-Au distance is reported. The observed enhancement can be partially explained by increased absorption cross section for QDs on metal islands; QDs near metal illuminated by both direct and a reflected beam, which increase the incident intensity. However the major enhancement is due to the increase in the electric field at QDs when the incident field excites the transverse collective resonances of metal islands. Room temperature photoluminescence (PL) spectra of sample are recorded. ; PUBLISHED
