An influence of surface modification on the carbon nanoparticles photoluminescence

摘要

We demonstrate an effective one-pot synthesis of blight-yellow carbon nanoparticles (CNPs) with thephotoluminescent (PL) maxima at the area around 600 nm. Hydrothermal synthesis was used as fast and cheap way forone-step CNPs synthesis and modification. Sodium dextran sulfate (DSS) was used as the main precursor for thesynthesis; polyethylene glycol based polymer (Jeffamine) and concentrated phosphoric acid were considered as surfacepassivation agents. The synthesized CNPs have typical for CNPs excitation-dependent PL.
