Emission-tunable microwave synthesis of highly luminescent water soluble CdSe/ZnS quantum dots.
Water soluble CdSe/ZnS nanoparticles with emission maxima from 511 nm to 596 nm and quantum efficiencies ranging from 11% to 28% are synthesized in a facile two-step method in ambient atmospheric conditions using a commercially available microwave reactor.
