The ECL behaviours of the RGO\u2013CdTe QD modified electrode were investigated with H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> as the co\u2010reactant. Quantitative detection of Cu<jats:sup>2+<\/jats:sup> was realized as Cu<jats:sup>2+<\/jats:sup> could effectively quench the ECL signal of the RGO\u2013CdTe QDs.

The proposed sensor also exhibited good stability and selectivity for the detection of copper ions.
