The stabilizer was shown to play an important role in both the sensitivity and selectivity for the determination of Cu<jats:sup>2+<\/jats:sup>. TGA\u2010capped CdTe QDs showed the highest sensitivity, followed by the MPA and GSH\u2010capped CdTe QDs, respectively. The TGA\u2010 and MPA\u2010capped CdTe QDs were not selective for Cu<jats:sup>2+<\/jats:sup> that was affected by Ag<jats:sup>+<\/jats:sup>. The GSH\u2010capped CdTe QDs were insensitive to Ag<jats:sup>+<\/jats:sup> and were used to determine Cu<jats:sup>2+<\/jats:sup> in water samples. Under optimal conditions, quenching of the fluorescence intensity (<jats:italic>F<\/jats:italic><jats:sub>0<\/jats:sub>\/<jats:italic>F<\/jats:italic>) increased linearly with the concentration of Cu<jats:sup>2+<\/jats:sup> over a range of 0.10\u20134.0 \u00b5g\/mL and the detection limit was 0.06 \u00b5g\/mL. The developed method was successfully applied to the determination of Cu<jats:sup>2+<\/jats:sup> in water samples. Good recoveries of 93\u2013104%, with a relative standard deviation of &lt; 6% demonstrated that the developed simple method was accurate and reliable. The quenching mechanisms were also described.
