Abstract
Photoinduced interaction of thioglycolic acid (TGA) capped CdTe quantum dots (QDs) with certain antioxidants such as estrogens and flavonoids has been investigated by using steady state and time resolved fluorescence spectroscopy. Reduction of electron-hole recombination has been observed (i.e., fluorescence quenching) while adding antioxidants to CdTe QDs. The Stern-Volmer constant (K-SV), quenching rate constant (k(q)) and binding constants (K) were obtained from fluorescence quenching data. The antioxidant interacts with QDs through static quenching, which was confirmed by unaltered fluorescence lifetime.
