Sputtering Power

WO3 -incorporated C–TiO2 nanotubes were successfully fabricated using radio frequency sputtering technique. The effects of sputtering powers on the nanotube morphology, crystal structure, optical properties and visible photoresponse were investigated. Lattice substitution of WO3 species within the lattice of C–TiO2 nanotubes has an important function in maximizing the photocurrent generation. WO3 -incorporated C–TiO2 nanotubes exhibit good visible photoresponse compared with C–TiO2 nanotubes. The interpretation of interband states has an important function in improving photoinduced electron transport.

We fabricated Si:SiO2 films including silicon nanocrystallites as one of nanoscale materials, which were prepared by co-sputtering of silicon and silicon dioxide. Optical properties of these films were analyzed by photoluminescence spectroscopy. Specimens fabricated at higher pressure between 0.3 Pa to 0.9 Pa emitted photoluminescence strongly. Photoluminescence was strong at shorter wavelength. In case fabricated in same Ar gas pressure, specimens that had composition ratio, 0.04, of the silicon for target emitted the photoluminescence strongly. Peaks existed on some PL spectra of specimen fabricated by the Ar gas pressure 0.3, 0.5 Pa and the composition ratio 0.04. Suppose that silicon nanocrystallites were fabricated, these size were few nm.
