Abstract
Hybrid crystalline organic-inorganic quantum confined systems are disclosed, which contain alternating layers of a bifunctional organic ligand and a II-VI semiconducting chalcogenide, wherein the semiconducting chalcogenide layers contain chalcogenides have the formula MQ, in which M is independently selected from II-VI semiconductor cationic species and Q is independently selected from S, Se and Te; and the bifunctional organic ligands of each organic ligand layer are bonded by a first functional group to an element M of an adjacent II-VI semiconducting chalcogenide layer and by a second functional group to an element M from the adjacent opposing II-VI semiconducting chalcogenide layer, so that the adjacent opposing II-VI semiconducting chalcogenide layers are linked by the bifunctional organic ligands of the organic ligand layers. Optical absorption experiments show that these systems produce a significant blue shift in their optical absorption edges, 1.2-1.5 eV, compared to a shift of 1.0 electron volt by the best grown II-VI or II-V semiconducting quantum colloidal dots. In addition, the II-VI confined layers in these systems possess a perfectly periodic arrangement.
