Multi-walled carbon nanotubes (MWNTs)/Cu-doped ZnO composite powders were prepared by co-precipitation method, and were characterized by X-ray diffraction, electron microscopy, fluorescence spectrum, and ultraviolet spectrum. Experimental results show that the MWNTs can be modified by Cu-doped ZnO nanoparticles with hexagonal wurtzite structure after annealed at 450 °C, and the nanoparticle siz...
A cadmium tetrahydroisoquinoline dithiocarbamate (DTC) complex has been used as single-source precursor for the synthesis of highly faceted hexadecylamine (HDA) capped CdS nanoparticles. Hexagonal and close to cubic shaped particles with distinct lattice fringes are visible in the high resolution transmission electron microscopy images. Crystalline particles in the shape of a hexagon are clearl...
Controlled cracking pattern formation in carbon-coated CZTS (CZTS@C) thin-film as high-power anodes for next-generation LIBs applications.
Self-assembled secondary ZnO nanoparticles, recognized with the agglomeration of crystalline subcrystals, are successfully synthesized by a simple sol-gel method. TEM images display that one artificial cluster behaves in a single-crystal-like wurtzite structure because subcrystals coagulate as the same crystal orientation. Moreover, from the resonant Raman scattering, the as-grown sample exhibi...
Zr doped ZnO nanoparticles are prepared by the sol-gel method with post-annealing. X-ray diffraction results show that all samples are the typical hexagonal wurtzite structure without any other new phase, as well as the Zr atoms have successfully entered into the ZnO lattices instead of forming other lattices. Magnetic measurements indicate that all the doping samples show room temperature ferr...
The first production of weakly agglomerated zinc selenide nanopowders by evaporation a target the required chemical composition in argon using fiber ytterbium laser is reported. Nanoparticles have shape polyhedrons and, more rarely, spheres with an average size 18 nm. According to XRD data, obtained contain two phases: stable cubic phase (sphalerite, 40 wt.%) and metastable hexagonal (wurtzite,...
Nanoparticles of the Cd1 2 xZnxSe alloy with different stoichiometries (x ~ 0.1, 0.2, 0.3) have been prepared using the microwave-assisted polyol method. In this simple and quick reaction the polyol (ethylene glycol) is both the solvent and the reducing agent. XRD studies show that nanoparticles are formed in the wurtzite (hexagonal) form with an average diameter of the nanocrystals of 5–8 nm. ...
Nearly monodisperse Cu-In-S ternary nanocrystals with tunable composition, crystalline structure, and size were synthesized by a hot-injection method using mixed generic precursors. Such ternary nanocrystals with zincblende and wurtzite structure were reported for the first time. This work correlates the crystalline structure of the binary ZnS nanoparticles with those of ternary Cu-In-S nanocry...
