Heavy carbon nanodots 2: plasmon amplification in Quanta Plate™ wells and the correlation with the synchronous scattering spectrum.

Brominated carbon nanodots are a new carbon nanostructure that exhibits strong phosphorescence without fixation. Herein we report plasmonic amplification of this phosphorescence in silver-coated Quanta Plate™ wells, a technique called metal-enhanced phosphorescence (MEP). Subsequently we correlate the excitation and emission components of brominated carbon nanodots to their respective enhancement values. These properties are then discussed in relation to the synchronous scattering spectrum of the plasmonic substrate, in the first report of its kind for MEP. These results set the foundation for expanded application of carbon nanodots, as the photophysical characteristics of phosphorescence are improved, and augment the growing understanding of MEP.
