Surface Plasmon Enhanced Photoluminescence of Carbon Dots Formed In Situ on Silver Gratings
Advanced Science, EarlyView.Carbon emitters formed in situ on a silver grating via plasmonic catalysis yield enhanced spontaneous emission by preferential radiative decay into surface plasmons. Enhancement manifests as emission exhibiting characteristics of coherence (polarization, directionality), and accelerated lifetimes of ∼30 ps, yielding Purcell factors of ∼70.
