Abstract

In this work, Au nanoparticle clusters are formed at nanoscale, covered by a polymer shell and decorated with CdS/CdSe QDs. The polymer layer serves as an insulator to prevent the fluorescence quenching. The variations in the density of photon states in similar disordered structures are analyzed through changes in the transition rates of the light emitters interacting with the hotspot regions. The localized surface plasmon modes are demonstrated to significantly alter the density of electromagnetic states with their unique characteristics at nanoscale, offering an alternative to sophisticated plasmonic devices to alter light-matter interaction.
