Top: Construction of small band gap In2Te3 quantum dots (~1.2 nm) in solid state. We demonstrate here the first perfectly ordered semiconductor QD crystal lattice. Bottom-Left: Optical absorption spectra of the parent structure In2Te3 and the hybrid In2Te3(L). A blue shift of ~1.8 eV is observed. Bottom-Right: Largely enhanced quantum efficiency of white light emission of hybrid [Zn2S2-2xSe2x(ba)] systems.
