Enhanced Room-TemperaturePhosphorescence from CarbonDots Embedded in a Robust SiO2 Matrix

Abstract Carbon dots (CDs) represent a rapidly advancing class of fluorescent nanomaterials. Due to the dominant nonradiative decay channels of the triplet excited state of CDs, these materials generally exhibit no observable phosphorescence (PH) or delayed fluorescence. Here, we...
