Abstract

From all types of plasmonic and photonics nanostructures developed for room-temperature single-photon source applications the highest Purcell factor with increasing emitter radiative decay rate and enhancement in the total fluorescence intensity were obtained with metal plasmonic patch (gap) nanoantennas. We report on sporadic appearance of ultrabright intensity spikes (up to ~400─900 kcounts/s) in time traces of photoluminescence from 100-nm silver nanocubes (widely used in patch plasmonic nanoantennas) under 532 or 633 nm laser excitation. Possible mechanisms of spikes are discussed.
