摘要(Abstract)：

为灵敏快速检测碘离子(I~-),以柠檬酸和乙二胺为原料,通过一步水热法合成具有蓝色发射的荧光碳点CDs。通过透射电子显微镜(TEM)、紫外-可见吸收光谱(UV-vis)、傅里叶变换红外光谱(FTIR)和荧光光谱对CDs的结构和光学性能进行表征;并采用CDs检测水样中的I~-,考察其检测效果和淬灭机理。结果表明:I~-可以特异性识别并淬灭CDs的荧光,淬灭机理为静态淬灭;I~-浓度与CDs的荧光强度在20～90μmol/L范围内具有良好的线性响应,检测限为1.743μmol/L;加标回收试验表明该方法可成功应用于真实水样中I~-的检测。

关键词(KeyWords)： 碳点;荧光;碘离子;检测;淬灭机理
