主　　题：Carbon dots Solvothermal Dual properties Fe3+ions detection Bioimaging 

摘      要：The excitation wavelength-dependent and-independent emissions are two crucial fluorescent properties of carbon dots(CDs).However,CDs reported till date exhibit only one of these properties,which limits their practical ***,dual-property carbon dots(DCDs)with both the excitation wavelength-dependent and-independent emissions were synthesized via a facile onestep solvothermal method using 4-(2-pyridylazo)-resorcinol as the carbon *** multi-functional applications of the resulting DCDs were also *** asprepared DCDs exhibited not only excellent monodispersity,high photostability,and storage stability,but also low toxicity,good biocompatibility,and cellular bioimaging *** addition,the DCDs exhibited excitation-dependent emission photoluminescence under low excitation *** DCDs exhibited good Fe3+detection by quenching the blue emission fluorescence and showed a relatively low Fe3+detection limit of 0.067 lmol·L-1 based on three times signal-to-noise criteria(R2=0.99).Furthermore,the DCDs showed excitation-independent emission at low excitation wavelengths and exhibited red emission at about 598 nm to avoid damage to the *** results demonstrate the excellent bioimaging properties of the *** to their dual PL properties,the as-prepared DCDs exhibited multi-functional applications:Fe3+detection and A549 cell *** results will be helpful in developing novel CDs for applications in various fields.
