Herein, the ECL behaviors of precise mono-Cu+ ion doped Cd–In–S supertetrahedral chalcogenide nanoclusters (Cu@CdInS NCs) were investigated, and the effect of mono-Cu+ ions at the vacancy site of NCs on ECL emission performance was also elucidated. Precise mono-Cu+ ion doping not only induced new ECL emission at 596 nm with enhanced efficiency as high as 21.72% relative to [Ru(bpy)3]2+, but also improved acid tolerance of the ECL performances of NCs. In addition, a simple, fast and label-free dopamine ECL sensor with excellent selectivity was achieved.

精确的单铜+离子掺杂增强了Cd-In-S超四面体硫族化物纳米簇中多巴胺检测的电化学发光

在此,研究了精确掺杂单Cu +离子的Cd-In-S超四面体硫族化物纳米簇(Cu @ CdInS NCs)的ECL行为,并且在NCs空位处单Cu +离子对ECL发射性能的影响为也阐明了。精确的单铜+离子掺杂不仅诱导了在596 nm处的新ECL发射,相对于[Ru(bpy)3 ] 2+效率提高了21.72%,而且还提高了NC的ECL性能的耐酸性。此外,还实现了一种简单,快速且无标签的多巴胺ECL传感器,具有出色的选择性。
