Fourier transmission infrared spectroscopy, X\u2010ray diffraction, transmission electron microscopy, ultraviolet\u2010visible and photoluminescence spectroscopy were used for characterization of the QDs. Based on the quenching effect of Cu<jats:sup>2+<\/jats:sup> ions on the fluorescence intensity of DPA\u2010capped CdTe QDs, a new fluorometric sensor for copper(II) detection was developed that showed good linearity over the concentration range 5\u2009\u00d7\u200910<jats:sup>\u20139<\/jats:sup>\u20133\u2009\u00d7\u200910<jats:sup>\u20136<\/jats:sup>\u2009<jats:sc>m<\/jats:sc> with the detection limit 0.4\u2009\u00d7\u200910<jats:sup>\u20139<\/jats:sup>\u2009<jats:sc>m<\/jats:sc>. Owing to the strong affinity of the DPA to copper(II), the sensor showed appropriate selectivity for copper(II) compared with conventional QDs. The DPA\u2010capped CdTe QDs was successfully applied for determination of Cu<jats:sup>2+<\/jats:sup> concentration in river, well and tap waters with satisfactory results.
