Mechanisms of photoluminescence in the molecular state of carbon dots prepared from o-phenylenediamine
Carbon dots(CDs)is an emerging photoluminescent(PL)carbon nanomaterial.Since its discovery in 2004[1],CDs have been used in a wide range of applications such as sensing,optical devices,in-vitro imaging,in-vivo imaging and phototherapy due to their ex-cellent PL properties[2,3].However,the intrinsic PL mechanism of CDs remains unclear,and a unified mechanism has not been achieved due to the different structures of various CDs.Therefore,the investigation of the PL mechanism of CDs is necessary and ur-gent to reveal the structure of CDs,to better guide the synthesis and to promote the deeper applications of CDs.
