Paper Abstract

A key application of metallic nanostructures is enhancement of the radiative decay rates of quantum emitters. In this contribution we investigate control of emission dynamics of semiconductor quantum dots (QDs) using combination of both metal oxides and plasmonic effects of gold thinfilms. Different metal oxides, including Cu, Ag and Al oxides are investigated. We show how such oxides can dramatically change the decay of QDs via photocatalytic processes in the absence and presence of plasmonic fields. The outcomes show the distinct impact of such oxides, ranging from total annihilation of QD emission to their plasmonic revival via Purcell effect.
