Chiral quantum dots

Abstract:
Fluorescent semiconductor nanoparticles that exhibit chiral luminescence have been made by scientists from Ireland ("Chiral highly luminescent CdS quantum dots").

Gun'ko's team prepared the chiral CdS QDs by heating the naked QDs with either left- or right-handed forms (enantiomers) of penicillamine. These gave off a bright green-white light when excited with UV light. When a fifty-fifty (racemic) mixture of the two enantiomers was used, the QDs gave off a bright blue-white light instead.
