Intense ultraviolet emission from needle-like WO3 nanostructures synthesized by noncatalytic thermal evaporation

Photoluminescence measurements showed that needle-like tungsten oxide nanostructures synthesized at 590°C to 750°C by the thermal evaporation of WO3 nanopowders without the use of a catalyst had an intense near-ultraviolet (NUV) emission band that was different from that of the tungsten oxide nanostructures obtained in other temperature ranges. The intense NUV emission might be due to the local...

Intense Diffuse Far-ultraviolet Emission from the Orion Nebula

We present spectra of the diffuse far-UV (900–1200 ) emission from a region near the Orion Nebula: the Å first high-resolution spectra of the diffuse background radiation. These observations were made using serendipitous Far Ultraviolet Spectroscopic Explorer (FUSE) observations and were only possible because of the strength of the diffuse emission (≈ photons cm 2 sr 1 s 1 ) and the sensitivity...

Surface Morphology and Sensing Property of NiO-WO3 Thin Films Prepared by Thermal Evaporation

WO3 and NiO-WO3 thin films of various thicknesses were deposited on an Al2O3-Si (alumina-silicon) substrate using high vacuum thermal evaporation. After annealing at 500C for 30 minutes in air, the crystallanity and surface morphology of WO3 and NiO-WO3 thin films were investigated using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). It is observed that the WO3 thin films were ...

Removal of Micrometer Size Morphological Defects and Enhancement of Ultraviolet Emission by Thermal Treatment of Ga-Doped ZnO Nanostructures

Mixed morphologies of Ga-doped Zinc Oxide (ZnO) nanostructures are synthesized by vapor transport method. Systematic scanning electron microscope (SEM) studies of different morphologies, after periodic heat treatments, gives direct evidence of sublimation. SEM micrographs give direct evidence that morphological defects of nanostructures can be removed by annealing. Ultra Violet (UV) and visible...

Seed/catalyst-free growth of zinc oxide nanostructures on multilayer graphene by thermal evaporation

We report the seed/catalyst-free growth of ZnO on multilayer graphene by thermal evaporation of Zn in the presence of O2 gas. The effects of substrate temperatures were studied. The changes of morphologies were very significant where the grown ZnO structures show three different structures, i.e., nanoclusters, nanorods, and thin films at 600°C, 800°C, and 1,000°C, respectively. High-density ver...
