Abstract

This work involves fluorescent probe which is composed of carbon dots (CD) and cadmium sulfide quantum dots (CdS QD) for the sensitive and selective fluorescence detection of chromium(vi) ions. The blue fluorescent carbon dots were synthesized by hydrothermal method from natural precursor apricot. The carbon dots-cadmium sulfide quantum dots (CD-CdS QD) nanocomposite was synthesized and all as-synthesized products were characterized using different characterization techniques. It showed white fluorescence under UV light which was quenched selectively in the presence of chromium(vi) ions due to the inner filter effect (IFE). The linear decrease in the white fluorescence was observed in the concentration range 2-120 μM of chromium(vi) ions with the limit of detection 2.07 μM. This is novel probe for the sensitive, selective and rapid detection of chromium(vi) ions.

摘要

这项工作涉及一种由碳点（CD）和硫化镉量子点（CdS QD）组成的荧光探针，用于灵敏且选择性地荧光检测六价铬离子。蓝色荧光碳点通过水热法由天然前体杏子合成。合成了碳点 - 硫化镉量子点（CD - CdS QD）纳米复合材料，并且使用不同的表征技术对所有合成产物进行了表征。它在紫外光下呈现白色荧光，由于内滤效应（IFE），在六价铬离子存在时该荧光被选择性猝灭。在2 - 120 μM六价铬离子浓度范围内观察到白色荧光呈线性下降，检测限为2.07 μM。这是一种用于灵敏、选择性和快速检测六价铬离子的新型探针。
