Investigation into the fluorescence quenching behaviors and applications of carbon dots.
Nanoscale, 2014Carbon dots (CDs) are novel fluorescent materials with low toxicity and good biocompatibility. Herein, the collisional/dynamic and photoluminescence (PL) center destruction quenching behaviors of a novel type of CDs were investigated.
