Abstract:
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.

Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
