Type-II core/shell quantum dots are characterized by a staggered alignment of conduction and valence bands (see Figure), giving rise to broad tunability absorption emission wavelengths. Colloidal ZnTe/CdE (E = S, Se, Te) have been prepared with yields up 30 %. The synthesis route presented should be applicable other type-II dots.
