Positron annihilation studies of silicon-rich SiO2 produced by high dose ion implantation
Positron annihilation spectroscopy ~PAS! is used to study Si-rich SiO2 samples prepared by implantation of Si ~160 keV! ions at doses in the range 3310–3310 cm and subsequent thermal annealing at high temperature ~up to 1100 °C!. Samples implanted at doses higher than 5 310 cm and annealed above 1000 °C showed a PAS spectrum with an annihilation peak broader than the unimplanted sample. We disc...
متن کاملPositron annihilation lifetime spectroscopy in nickel ferrite and iron oxide nanopowders
In this study, a positron annihilation lifetime spectrometer was set up and its resolution was optimized. The spectrometer is a fast-slow arrangement with time resolution of 250 ps. To obtain lifetime components and their intensities from analyzing positron annihilation lifetime spectrum, the Pascual software is used. Positrons are from a source of radioactive 22NaCl with 20 μCi activity enclos...
متن کاملSynthesis and nano structural study on TiO2-NiO-SiO2 composite
We report on the synthesis, morphology, chemically and structurally of TiO2-NiO-SiO2 nanostructure. The TiO2-NiO-SiO2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. The coatings were deposited on dried soda-lime glass slides by spin coating. Composite powders and coating on glass hav...

متن کاملPositron Annihilation Spectroscopy: A Review of Applications in Nanomaterials Thin films and Semiconductors
A brief review have been presented highlighting the use of positron annihilation spectroscopic techniques for exploring the physical properties of materials from bulk to nanocrystalline sized particles. Even though a direct correlation of the changed annihilation characteristics with predictable changes in the solid is certainly not possible, positron annihilation can be used for obtaining comp...
