This article reports on the first attempt of a systematic study on the synthesis of carbon dots (C-dots) for the potential applications in labeling and detection of molybdenum ion (Mo ). Carbon dots (C-dots) were synthesized directly via a simple hydrothermal method using lemon juices as carbon precursor with different temperatures to control the luminescence of C-dots. The obtained C-dots had strong green light emission and the ability to use its luminescence properties as probes for Mo detection application, which is based on Mo induced luminescence quenching of C-dots. This analysis system exhibits strong sensitivity and good selectivity for Mo ion, and a detection limit as low as 20 ppm is achieved. These results suggest that the present C-dots have potential application in optoelectronic, labeling and luminescent probing of Mo ions.
本文报道了首次尝试对用于钼离子（Mo）标记和检测潜在应用的碳点（C-点）合成进行系统研究。通过简单的水热法，以柠檬汁为碳前驱体，在不同温度下直接合成碳点（C-点），以控制C-点的发光。所获得的C-点发出强烈的绿光，并具有利用其发光特性作为钼检测应用探针的能力，该应用基于钼诱导的C-点发光猝灭。该分析系统对钼离子具有很强的灵敏度和良好的选择性，检测限低至20 ppm。这些结果表明，目前的C-点在钼离子的光电、标记和发光探测方面具有潜在应用。
