Abstract

We examined the interdot energy transfer between monodisperse quantum dots under different degrees of plasmonic effects (plasmonic field enhancement and Forster energy transfer from quantum dots to metallic nanoparticles). For this we studied emission of CdSe/ZnS quantum dots deposited on substrates containing self-organized arrays of gold nanoislands with radially distributed sizes gradually reduced from the centers of the substrates to their sides. The results suggest how metallic nanoparticles can be used to enhance interdot energy transfer in monodisperse quantum dots and how this process can explain some of the spectral changes seen in the emission of quantum dots when they are close to the metallic nanoparticles.
