We have demonstrated that variation of the precursor concentration during hydrothermal synthesis of carbon nanodots is an efficient mean to tune the yield of the products keeping their optical properties the same. Moreover, we found that the nature of the precursor determined the sensitivity and selectivity of detection of metal ions in the solution via quenching the fluorescence.

使用来自各种来源的碳纳米点进行金属离子传感

我们已经证明，在碳纳米点的水热合成过程中，前体浓度的变化是调整产品产量保持其光学性质相同的有效手段。此外，我们发现前体的性质决定了通过猝灭荧光检测溶液中金属离子的灵敏度和选择性。
