Bayliss Seminar Series : Cd-free One-dimensional Colloidal Semiconductor Nanocrystals Other events...
Quasi-one-dimensional (1D) colloidal semiconductor nanocrystals manifest linearly polarized emission, reduced lasing threshold, and improved charge transport compared with spherical quantum dots, and find diverse applications ranging from optics, electronics, photocatalysis, sensors to biology. In the first part of this talk, I will present a new type of nanostructure, “nanorod couples”, composed of two closely spaced nanorods fused together at both ends via the formation of a twinning structure formed by a self-limited self-assembly mechanism. On top of the detailed synthetic, structural and mechanistic growth study, the properties of the nanorod couples are also studied and modeled showing how the system morphology and geometry directly affects the optical and electronic properties. Secondly, I will introduce a new growth mechanism to synthesize ZnSe nanorods, which involves an intraparticle ripening process from their respective ultrathin nanowires through the thermodynamically driven material diffusion. Moreover, this synthetic strategy has been successfully expanded to other Zn-chalcogenides nanorods systems, including ZnS and ZnTe, demonstrating the generality of this synthetic approach. The availability of cadmium free (or “green”) zinc chalcogenides quantum rods synthesized through this strategy bares significant applicative importance and paves the way for its use in optics, photocatalysis, electronic devices and bio-labeling.
