| Annotation | Methodology for treatment of positron annihilation lifetime spectra by LT computer program in the nanostructured ceramic materials was proposed. Features of mathematical description of annihilation spectra was demonstrated. The algorithm for selection of optimum values of fitting and positron trapping parameters in nanovoids was shown. Annihilation spectra were analyzed for functional temperature-sensitive ceramics using LT program at different amount of components. It is shown that three-component fitting procedure enables to define the radius of nanopores in functional ceramic materials. |
