Measurable emission color change: Size-dependent reversible fluorescence quenching of CdTe quantum dots by molecular oxygen
The measurable emission color change resulting from size-dependent quenching of water-soluble CdTe quantum dots by molecular oxygen was observed experimentally. Particle size, capping ligands as well as pH is proven to govern this quenching process.
