Single step synthesis of size-controlled carbon quantum dots using electrochemical etching of graphite
英文摘要：
Carbon Quantum dots (CQD's) are nanoscale sp2 hybridized carbon particles. In this work, we present a simple one-step synthesis of CQDs from the electrochemical shredding method and technique to control its size during its growth process. A graphite rod extracted from commercially available pencil batteries was used as electrode: source of carbon. CQDs of varying sizes were synthesized through controlled current to the solution for etching and Sodium dodecyl sulfate (SDS) as capping agent during growth. CQD's of controlled sizes as formed can be used as fluorescent marker for bio-imaging and sensing platform for wide range of applications.
