Photoinduced IR absorption measurements are reported on WO3. A photoinduced midinfrared small polaron peak centered at 4800 cm−1 (0.59 eV) was observed. The data were analyzed in the framework of the photon-assisted small-polaron hopping theory and briefly compared to previously published infrared absorption measurements in WO3 and photoinduced IR absorption measurements in high Tc cuprates. PA...

Radiotherapy which consists of external beam radiotherapy (EBRT) and internal radioisotope therapy (RIT), has a wide usage for treating cancer as clinical trials.This study provides some conditions to prove that tungsten oxide nanoparticles (WO3) is a radiosensitizer.The peripheral blood mononuclear cells (PBMCs) were used to calculate inhibitory concentration (IC).The AGS cell line exposed the...

The photoelectrolysis of water to yield hydrogen and oxygen using visible light has enormous potential for solar energy harvesting if suitable photoelectrode materials can be developed. Few of the materials with a band gap suitable for visible light activation have the necessary band-edge potentials or photochemical stability to be suitable candidates. Tungsten oxide (Ebg 2.8 eV) is a good cand...

The radiation shielding abilities of waste marbles with different concentrations WO3 (tungsten oxide) nanoparticles were investigated. Four prepared 0, 0.05, 0.1, and 0.2 nanoparticles. study aims to investigate the effect concentration, density, particle size marble samples. linear attenuation coefficient (LAC) S1 sample, sample no WO3, was determined theoretically experimentally, results demo...

We report the effect of inert gas (argon and helium) along with different concentrations of oxygen on the structural and optical properties of the rf magnetron sputtered nanocrystalline tungsten oxide thin films. The crystal structure and surface morphology were studied by X-ray diffraction (XRD) and atomic force microscope (AFM), respectively. We find that the atomic mass of the sputtering gas...

Transition-metal dichalcogenides (TMDs) nanostructures including nanotubes and monolayers have attracted great interests in materials science, chemistry to condensed matter physics. We present an interesting study of the vibration modes in multi-walled tungsten sulfide (WS2) nanotubes prepared via sulfurizing tungsten oxide (WO3) nanowires which are investigated by confocal micro-Raman spectros...
