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 Sn and Mo ions. This probe had a fast response time at pH = 4 with high sensitivity and selectivity. Linear correlation between F/F and the concentration was seen in the range of 0.2-18 μM and 0.2-25 μM for Sn and Mo, respectively. Under optimum condition, the limit of detection (LOD) for Sn and Mo were 150 nM and 132 nM, 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.
采用一种绿色简便的微波辅助方法合成了水溶性硼氮共掺杂碳点（B-N-CDs）。这些B-N-CDs成功用于荧光测定锡和钼离子。该探针在pH = 4时响应时间快，具有高灵敏度和选择性。对于锡和钼，F/F与浓度之间的线性相关范围分别为0.2 - 18 μM和0.2 - 25 μM。在最佳条件下，锡和钼的检测限（LOD）分别为150 nM和132 nM。通过不同的实际样品如自来水、河水、矿泉水、罐装鱼样品和番茄样品对该传感器的性能进行了评估。
