title: Facile synthetic strategy for efficient and multi-color fluorescent BCNO nanocrystals.
abstract: A facile strategy based on the reaction of urea and boric acid is developed for the synthesis of toxicity-free BCNO nanocrystals containing carbon impurities and which exhibit efficient multi-color fluorescence under both single-photon and two-photon excitation.
