摘要：
Herein, we prepared water-soluble fluorescent carbon dots with diameter about 1.5 nm from cheap commercial lampblack. These fluorescent carbon nanoparticles are stable toward photobleaching and stable in water for more than half a year without fluorescence decrease. In order to improve its fluorescence properties, we passivated these nanoparticles with bisamino-terminated polyethylene glycol (PEG(1500N)). Therefore, both fluorescence quantum yield and lifetime increased after this progress. in addition, the passivated carbon dots were more inert to solvent than the bare one and showed different responses to pH change.
