zno nanowires with a diameter of 70 nm and nanorods with a diameter in the range of 100-150 nm and two micrometer in length were grown on glass substrates by resistive evaporation method and applying a two step oxidation process at low temperatures, without using any catalyst, template or buffer layer. xrd pattern of these nanostructures indicated a good crystallinity property with wurtzite hex...

Coulomb repulsion due to the surface charge on semi-conductor nanorods works against the dipole-dipole attraction that tends to direct the nanorods to self-assemble; the nature of this self-assembly for CdSe nanorods can be thus altered by pyridine washing, which charges the rods surface--thereby allowing the Coulomb repulsion to tailor the alignment.

CuGaS(2) nanorods were synthesized by irradiating the precursor solution with intense X-rays. The products are single crystal nanorods with preferential [220] growth and a uniform size distribution. We also report on the photoresponse of drop-cast films of these nanorods.

When controlling the assembly of magnetic nanorods and chains of magnetic nanoparticles, it is extremely challenging to bring them together side by side while keeping a desired spacing between their axes. We show that this challenge can be successfully resolved by using a non-uniform magnetic field that defeats an inherent repulsion between nanorods. Nickel nanorods were suspended in a viscous ...

In this study, we synthesize high quality vertically aligned ZnO (VAZO) nanorods on silicon, sapphire, and indium tin oxide (ITO) substrates by using pulsed laser deposition (PLD) technique at high growth pressure (0.3 Torr). Systematic changes in structural and optical properties of VAZO nanorods are studied by varying the substrate temperature (500-600 °C) and number of pulsed laser shots dur...

a facile and simple method was proposed to control the size and shape of the mgo nano structures with high surface area in the presence of efficient and cheap templates like peg 200, peg 600, peg 4000 and sorbitol at low temperature within a little time. nano rods and nanoparticles have been achieved by applying these templates and altering other growth parameters. the products were characteriz...

cobalt ferrite (cofe2o4) nanorods were synthesized by iron chloride (fecl3.6h2o) and cobalt sulfate hexahydrate (coso4.7h2o) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (pvp) surfactant. the samples were characterized to identify the physical properties. xrd pattern of cobalt ferrite samples showed the structure of body center cubic (bcc) structure. the diam...

We report the solution-based synthesis of single-crystalline nanorods composed of barium titanate (BaTiO3) and strontium titanate (SrTiO3), which yields well-isolated nanorods with diameters ranging from 5 to 60 nm and lengths reaching up to >10 mum. Electron microscopy and diffraction measurements show that these nanorods are composed of single-crystalline cubic perovskite BaTiO3 and SrTiO3 wi...

Multiferroic ErMn2O5 nanorods have been synthesized via a surfactant-templated hydrothermal route. An environmentally friendly natural surfactant (Arabic gum) has been utilized as a template to prepare ErMn2O5 nanorods with a controllable morphology and size (i.e., nanorods with various lengths and basically invariable diameter). ErMn2O5 nanorods show strong size-dependent magnetic properties t...

Silica coated bismuth sulfide (Bi2S3) nanorods have been prepared by a simple coating process. The coating resulted in the improved stability and luminescent intensity of the Bi2S3 nanorods. Hollow silica nanotubes were also obtained by using Bi2S3 nanorods as a removal template. r 2005 Elsevier B.V. All rights reserved. PACS: 81.05.Ys; 81.20. n
