Plasmon mediated super-absorber flexible nanocomposites for metamaterials

Author affiliations

Abstract

A flexible host has been selected to achieve, for the first time, functional nanocomposites based on CdSe@ZnS core–shell type quantum dots (QDs) and Au nanoparticles (NPs), simultaneously dispersed in a polymer matrix. Coherent interactions between QDs and plasmonic Au NPs embedded in PDMS films have been demonstrated to lead to a relevant enhancement of the absorption cross-section of the QDs, remarkably modifying the optical response of the entire system. Optical and time resolved spectroscopy studies revealed an active gain-plasmon feedback behind the super-absorbing overall effect.
