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 …

In addition, a simple, fast and label-free dopamine ECL sensor with excellent selectivity was achieved.
