The paper is devoted to the changes in the X-ray luminescence spectra of nanoscale Y2O3 ceramics, namely the radiation associated with a self-trapped exciton. Additional heat treatment (annealing) of ceramic samples leads to changes in the exciton band of... see more

The paper presents the experimental results of light radiation from Y2O3 ceramics caused by X-rays with energy up to 50 keV. The samples were made from commercial Y2O3 nanopowder by pressing and subsequent sintering in air at different temperatures from 1... see more

This paper discusses the spectra of photo - and ion-luminescence (PL and IL) of ultrafine crystals (UDC) ZnO deposited on the substrate in an electric field. UDC ZnO was obtained by separation in a water emulsion industrial phosphor (K-56). The fluor... see more

This paper discusses the spectra of photo - and ion-luminescence (PL and IL) of ultrafine crystals (UDC) ZnO deposited on the substrate in an magnetic field. UDC ZnO was  obtained by separation in a water emulsion industrial phosphor (K-56). The... see more

Surface plasmons and excitons have been widely studied experimentally and theoretically for various material systems. However, a number of aspects require further deeper study and understanding, among which the connection of these quasi-particles occupies... see more

The work was explored the kinetics of the changes in the components of the liquid from Achilles tendon, that occur in the tissue of the Achilles tendon as a result of processes of autolysis, within 2-3, 4-6, 7-9 and 10-20 days post-mortem period. The gas-... see more

With the advantages of selectivity, spectral resolution and reduction of interference on account of light scattering, synchronous luminescence spectroscopy (SLS) is successfully applied to analyze complex mixtures with overlapped emission and/or excitatio... see more

The article presents the results of experimental studies of hydrodynamic processes in a cavitation generator. To study the mechanisms of cavitation and hydrodynamic luminescence, a basic hydraulic circuit of a test bench was developed and a bench was crea... see more
