Cadmium selenide nanowires from growth to applications

Cobalt-doped cadmium selenide colloidal nanowires.

Co(2+)-doped CdSe colloidal nanowires with tunable size and dopant concentration have been prepared by a solution-liquid-solid (SLS) approach for the first time. These doped nanowires exhibit anomalous photoluminescence temperature dependence in comparison with undoped nanowires.

Growth of Antimony Telluride and Bismuth Selenide Topological Insulator Nanowires

Topological insulators are a relatively new class of materials, which are insulating in the bulk and conductive on the surface. Surface conductance measurements of topological insulators are often obscured by impurities in the bulk. Nanowires made of a topologically insulating material provide a solution to this problem with their large surface-area-to-volume ratio. I examine the growth procedu...

Cadmium Selenide-Gold (CdSe-Au) Hybrid Nanowires: Synthesis and Study of Charge Transfer

White-light emission from magic-sized cadmium selenide nanocrystals.

Magic-sized cadmium selenide (CdSe) nanocrystals have been pyrolytically synthesized. These ultra-small nanocrystals exhibit broadband emission (420-710 nm) that covers most of the visible spectrum while not suffering from self absorption. This behavior is a direct result of the extremely narrow size distribution and unusually large Stokes shift (40-50 nm). The intrinsic properties of these ult...

Particle-rod hybrids: growth of arachidic acid molecular rods from capped cadmium selenide nanoparticles.

This communication describes a spin-coating method to nucleate organic molecular rods of uniform size from an inorganic nanoparticle at a solid surface. The particle-rod hybrid structure spontaneously forms when a film is spin coated from a mixed 2-propanol solution of arachidic acid (AA) and nanoparticles of cadmium selenide capped by mercaptoundecanoic acid (MUA-CdSe) on graphite. AFM images ...
