英文摘要the study of the composition, morphology, and surface structure of carbon dots (cdots) is critical to understanding their effect on the photo- and electrochemiluminescence (pl and ecl) of cdots in selected applications. herein, two kinds of cdots were prepared with 3-(3,4-dihydroxyphenyl)-l-alanine (l-dopa) as precursor. the cdots prepared by using a carbonization-extraction strategy have a low oxidation level and are denoted as reduced cdots (r-cdots). the cdots obtained with a carbonization-oxidation process are highly oxidized and are denoted as oxidized cdots (o-cdots). the o-cdots have a carbon core and oxygen-containing loose shell, but the r-cdots consist mainly of the carbon core. whereas r-cdots have a strong blue pl but no apparent ecl response, o-cdots exhibit a relatively weak pl and strong ecl emission. these properties allow for selected applications of the cdots. the r-cdots were used in cell imaging with their high pl emission. the o-cdots, with their high ecl efficiencies, were selected to sense cu2+ with cu2+-inducing ecl quenching in the o-cdots/k2s2o8 system. this work provides the possibility to control the composition of cdots for selected applications and shows a good way to characterize surface traps of cdots because ecl is characterized by the surface-state and pl is mainly related to the core-state in cdots.
