Abstract
In this paper, Zn doped CdTe quantum dots (CdTe:Zn QDs) was synthesized and imbedded in silica particles via a reverse microemulsion method to form a QDs/silica core. It acted as a fluorescence energy donor to conjugate with fluorescence energy acceptor rhodamine B derivative and construct a fluorescence sensor based on the principle of fluorescence resonance energy transfer (FRET). Hg2+ ions induced the ring-opening reaction of the spirolactam rhodamine moieties, leading to the occurrence of FRET. The fluorescence probe was accomplished by detecting the fluorescence intensity at 521 nm and 577 nm, and it exhibited high selectivity, sensitivity and accuracy and the detection limit reached as low as 0.5 µM.
