Abstract

In this paper, a new ratiometric fluorescent nanosensor was synthesized simply and economically and applied for Cu²⁺ detection in water samples. This nanosensor was a type of dual-emission quantum dots which was composed silica coated red CdTe quantum dots and glutathione modified green CdTe quantum dots. The probe exhibits a dynamic response range for Cu²⁺ from 6.7 × 10^-8 to 8 × 10^-7 mol L^-1 with a detection limit of 2.5 × 10^-8 mol L^-1. Other alkali, alkaline earth and transitional metal ions including K⁺, Na⁺, Mg²⁺, Zn²⁺, Pb²⁺, Ni²⁺, Cr³⁺ and Fe³⁺ had no significant interferences on Cu²⁺ determination. Binding Cu²⁺ to the nanosensor make the colour of the solution change from green to orange under UV light irradiation, which illustrates that this new sensor can realize visually detection of Cu²⁺.
