N-doped carbon dots with tunable emission for multifaceted application: solvatochromism, moisture sensing, pH sensing, and solid state multicolor lighting
A simple and high-output strategy for the fabrication of yellow fluorescent phosphorous and nitrogen co-doped carbon dots (P,N-CDs) is developed. P,N-CDs possess distinctive photoluminescence properties, low toxicity, and biocompatible. P,N-CDs are potentially useful for versatile applications such as pH sensing, in vitro and in vivo imaging.
Multi-doped carbon dots (C-dots) were synthesized by a facile one-pot solvothermal method, and the C-dots could be used as a ratiometric pH probe directly without integrating with other dyes, which was demonstrated by monitoring the proton-producing enzyme catalytic reactions.
