This paper presents an investigation on the fluorescent properties of semiconductor CdTe quantum dots (QDs) self-assembled on the surface of PVP (polyvinylpyrrolidone) capped silver nanoparticles (NPs) film by ligand field effect under the two photons excitation of 800nm femto second laser. A significant enhancement by 4.5-fold in the integrated fluorescence intensities, red shift of fluorescence...
We report a new optical data storage method: photomodification of hollow gold nanoparticle (HGN) monolayers induced by one-shot deep-ultraviolet (DUV) KrF laser recording. The short wavelength of the recording DUV laser improved the optical resolution dramatically.
This paper introduces a novel microfabrication method for engineered nanopore devices that does not require nanolithography. Nanopores are compositionally constructed at the intersection of two orthogonal sacrificial nanometer gap spacers. Arrays of rectangular nanopores 10 times 12 nm bounded by polycrystalline silicon and silicon nitride walls were fabricated on silicon nitride membranes. The nanopore...
FeCuNbSiB amorphous microwires with average diameter about 40 mum were fabricated by a specially designed melted quench facility. Anneal treatment at T=673K for 1 hour had been carried out for amorphous wires to obtain nanocrystalline grains with average grain diameter of 34 nm. Then, the heat treated microwires were cut into short fibers, the length and diameter ratio was about 2. The composite samples...
