Abstract
A green and simple microwave-assisted method was used to synthesis water-soluble boron and nitrogen-co-doped carbon dots (B-N-CDs). These B-N-CDs were successfully used for the fluorescent determination of Sn4+ and Mo6+ ions. This probe had a fast response time at pH=4 with high sensitivity and selectivity. Linear correlation between F0/F and the concentration was seen in the range of 0.2-18μM and 0.2-25μM for Sn4+ and Mo6+, respectively. Under optimum condition, the limit of detection (LOD) for Sn4+ and Mo6+ were 150nM and 132nM, respectively. The performance of the sensor was evaluated by different real samples such as tap, river and mineral water, canned fish sample and tomato samples.
