NIR-Emitting Colloidal Quantum Dots Having 26% Luminescence Quantum Yield in Buffer Solution

We report PbS quantum dot lumophores emitting in the near-infrared. The lumophores are stable for at least 5 days stored in physiologically relevant pH 6−8 buffer, have sub-10 nm hydrodynamic diameter, and exhibit 26% quantum yield.
