Thin films of the heavy-fermion system CeIn3 were prepared by simultaneous dc sputtering of two stoichiometric CeIn3 targets and dc magnetron sputtering of a pure indium target in argon gas. The films were grown at a high rate of ∼30 A/s on 10×20

Reprocessing of spent fuel produces high level waste including minor actinides and long living fission products that might be disposed in waste conditioning matrices. Several natural mineral phases were proven to be able to incorporate fission produc

Nano-particles of Au embedded in TiO2 (rutile) single crystals have been synthesized by 260 keV Au ion implantation up to a fluence of 5 × 1016 ions/cm2. Cross-sectional and high resolution transmission electron microscopy (TEM) has been utilized to

Some experimental results about thickness uniformity, composition uniformity, and stoichiometry of large-area multicomponent oxide thin films deposited by inverted cylindrical sputtering from a compound target were reported. Rutherford backscattering

Thermoluminescence of strontium titanate at low temperature is characterised by long wavelength emission centred near 800 nm which contains at least three overlapping luminescence bands. The thermoluminescence is excited by X-ray irradiation at 25 K

Cathodoluminescence is an effective tool for investigating phase changes and relaxation processes in insulators and data are presented for strontium titanate. The results demonstrate considerable sensitivity to the origin of the samples as the detail

Radioluminescence of strontium titanate has shown anomalous behaviour in that the signals from the bulk material are strongly modified as the result of ion beam implantation into the surface. During cooling of the implanted samples the red luminescen

Two-dimensionally (2D) ordered arrangements of Au micro-discs formed on the surfaces of TiO2 and SrTiO3 after “patterned” ion implantation. Cross-sectional TEM revealed that the Au micro-discs consisted of Au nanoparticles with a very narrow dept

The relative thickness distribution of large-area films deposited from an inverted cylindrical dc sputter gun with high gas pressure is calculated according to Feck’s diffusion law, based on a source-transformation method. The effects of the off-ax

CeO2 thin films were prepared on amorphous quartz glass substrates by the ion beam assisted deposition (IBAD) technique at room temperature. In order to control both the in-plane and out-of-plane texture of the films, a special geometrical arrangemen
