Abstract
A dissociative luminescent sensor for Ni2+, Co2+, and H+ ions in water solutions has been developed. This sensor is a complex made up of luminescent semiconductor hydrophobic CdSe/ZnS quantum dots (QDs) with azo-dye l-(2-pyridylazo)-2-naphthol (PAN). The luminescent properties of these complexes are investigated in organic solutions and in polymer matrixes. It is shown that the QD/PAN complex can be used for the quantitative luminescent analysis of Ni2+, Co2+, and H+ ions in water solutions with a significantly higher sensitivity than that of the traditional colorimetric methods of analysis.
