摘要
The important photoluminescence enhancement found in Carbon Dots (CDs) obtained from carbonaceous nanomaterials when passivating with acetone is shown in this paper, in which this type of passivation has not been reported previously. Analytical fluorescent assays were performed with the selected CDs using two different pollutants as target analytes. The results show that the optimal conditions for detecting 2,4-dinitrophenol (DNP) were at pH 3.5 while in case of 2-amino-3,4,8-trimethyl-3H-imidazo[4,5-f]quinoxaline (4,8-DiMeIQx) were found at physiological pH. The fascinating ability of CDs to interact with certain molecules under certain conditions gave rise to explore some useful applications for a quick detection of contaminants by simply monitoring the photoluminescence of CDs as shown in this article.
