Aqueous synthesis of zinc blende CdTe/CdS magic-core/thick-shell tetrahedral-shaped nanocrystals with emission tunable to near-infrared.
We demonstrate the synthesis of near-IR-emitting zinc blende CdTe/CdS tetrahedral-shaped nanocrystals with a magic-sized (approximately 0.8 nm radius) CdTe core and a thick CdS shell (up to 5 nm). These high-quality water-soluble nanocrystals were obtained by a simple but reliable aqueous method at low temperature. During the growth of the shell over the magic core, the core/shell nanocrystals ...
متن کاملSynthesis and Characterization of Water-dispersed CdSe/CdS Core-shell Quantum Dots Prepared via Layer-by-layer Method Capped with Carboxylic-functionalized Poly(Vinyl Alcohol)
The main goal of this work was to synthesize CdSe/CdS (core-shell) nanoparticles stabilized by polymer ligand using entirely aqueous colloidal chemistry at room temperature. First, the CdSe core was prepared using precursors and acid-functionalized poly(vinyl alcohol) as the capping ligand. Next, a CdS shell was grown onto the CdSe core via the layer-by-layer technique. The CdS shell was formed...
متن کاملCdTe/CdS core shell quantum dots for photonic applications
In this work, we show a simple experimental procedure to obtain CdTe/CdS (diameterZ3–7 nm) core shell nanocrystals in colloidal suspension. The nanocrystals were characterized by transmission electronic microscopy and powder X-ray diffraction analysis. The optical properties were determined by electronic absorption, excitation and emission spectroscopies and are discussed in terms of chemical c...
متن کاملSynthesis of Aqueous CdTe/CdS/ZnS Core/shell/shell Quantum Dots by a Chemical Aerosol Flow Method
This work described a continuous method to synthesize CdTe/CdS/ZnS core/shell/shell quantum dots. In an integrated system by flawlessly combining the chemical aerosol flow system working at high temperature (200-300 degrees C) to generate CdTe/CdS intermediate products and an additional heat-up setup at relatively low temperature to overcoat the ZnS shells, the CdTe/CdS/ZnS multishell structure...
متن کاملسنتز و بررسی خواص اپتیکی و ساختاری نانو ذرههای پوسته/هسته ZnS/CdS
In this research, CdS nanoparticles and core/shell CdS/ZnS nanoparticles were prepared by using aqueous solution method and used 3-mercaptopropionic acid (MPA) as capping molecule. The effect of ZnS shell on optical and structural properties of CdS was investigated. X ray diffraction patterns of CdS nanoparticles at the room temperature and after heat treatment show zinc blende structure. X ray...
