Abstract

Self-quenching in the aggregation state is overcome, and tunable solid-state photoluminescence of carbon-dot powder is achieved. Furthermore, based on the controllable optical property in organic solvents, a novel concept, i.e., constructing dual-fluorescence morphologies from single luminescent species, is presented to realize white-light emission.

Keywords: carbon dots; dual-fluorescence morphologies; self-quenching-resistance; tunable solid-state fluorescence; white-light-emission.
