Paper Abstract

Fluorescence of gold nanocubes is investigated down to the single-particle level using time-correlated single photon (SP) counting techniques with a combined confocal and atomic force microscopy system. In comparison with most fluorophores, gold nanocubes exhibit nonblinking and nonbleaching behavior at ambient environment with much faster fluorescence decay. Also, the photon statistics of single gold nanocubes follows a Poissonian distribution, unlike the SP emission characteristics of single semiconducting quantum dots. Therefore, from the single-particle perspective, the fluorescence of gold nanocubes is attributed to the radiative emission from excited localized surface plasmons.
