Single Nonblinking CdTe Quantum Dots Synthesized in Aqueous Thiopropionic Acid

Blinking marvelous! In contrast to quantum dots (QDs) synthesized in organic solutions, CdTe QDs synthesized in aqueous solutions containing thiopropionic acid do not blink. The fluorescence of these QDs is steady under continuous laser excitation (see picture, the gray line is the background intensity). The presence of thio groups on the surface of the QDs is key to their antiblinking behavior.
