Aqueous Phase Preparation of CdTe Nanorods and its Application in Recognition of Cu~(2+) Ions
Source abstract
Abstract
Optical-tunable CdTe nanorods were synthesized in aqueous solution using thioglycoclic acid and L-cysteine as co-stabilizing reagents.CdTe nanorods with dual-wavelength emission was appreciated as a novel fluorescent probe for copper ions.Copper ions display a significant quenching effect on the nanorods trap emission at 645nm and no effect on band-edge emission at 535nm.In a slight basic medium,the surface trap emission intensity of nanorods is proportional to the concentration of Cu2+ ion in the range from 0 to 2.8×10-6mol/L,and the corresponding limit of detection is 4.0×10-9mol/L.The mechanism of reaction between CdTe nanorods and Cu2+ ions are discussed in further.
