Abstract: P-doped carbon quantum dots (PCQDs) were synthesized by a solvent-thermal method using phosphorous tribromide and hydroquinone as precursors. The as-prepared PCQDs present strong visible fluorescence with quantum yield up to 25%. The toxicity and bioimaging experiments showed that PCQDs have low cell toxicity and excellent biolabeling ability.

“…31 In case of PCD iso , PCD gly and PCD val , in addition to the peaks for carbon, nitrogen and oxygen, two extra peaks were found at 134 eV and 191 eV which indicates the peaks correspond to 2p and 2s of phosphorous atom (P), respectively (Fig. 31,40 This characterization further established though little but successful doping of P in carbon dots. 31,40 This characterization further established though little but successful doping of P in carbon dots.…”

“…To improve the fluorescence quantum yield, a variety of dopants including N, S, B, P, and Si have been added during the synthesis of CDs. In our experiment, we employed EDA as both a passivation agent and an N dopant.…”

“…[23][24][25][26][27][28][29] Lanthanide-doped CQDs can act as new probes with near infra-red fluorescence or fluorescence/magnetic resonance dual response. [30][31][32][33] However, the development of functional CQDs doped with transition metal using fixed metal complexes as precursors is yet to be reported.…”
