One-step extracting high fluorescent carbon quantum dots by physical method from carbon black

Abstract

Herein, we introduced a kind of physical method, using acetone to directly extract fluorescent carbon quantum dots (CQDs) from ordinary carbon black by one step. The as-extracted CQDs exhibited an excitation-dependent emission behavior and high quantum yield up to 19.01%. Moreover, we find the polarity of the solvent will affect the size of CQDs for the first time.
