The effect of a weak magnetic field on stress relaxation in NaCl crystals after the termination of active deformation has been experimentally studied for the first time. The results indicate that stress relaxation is accompanied by the magnetoplastic

The work is a kind of summary of the articles published in the last decade. They deal with the investigation of the dosimetric properties of crystalline and ceramic magnesium oxide with the aim of its use as thermoluminescent detectors.

The subject of this research is the fluorescence lifetime of R line (2E→ 4A2 transition) in MgO:V2+ under high pressure. The goal is to obtain experimental results regarding the fluorescence lifetime τ for R line (2E→ 4A2 transition) in MgO:V2+

Thermally stimulated luminescence as well as optical absorption and emission spectra have been studied in LiF crystals irradiated in a reactor at different temperatures. It was shown that aggregate colour centres give rise to thermally stimulated lum

The luminescence of nominally pure magnesium oxide crystals irradiated in a nuclear reactor is studied. It is shown that, in the entire fluence range (1015–1018 n/cm2), the active luminescence centers are chromium impurity ions, which are initially

The combined action of UV-light and continuously increased mechanical stress on LiF single crystals preirradiated in the reactor prolongs the life-time of F2+ centers unstable at room temperature. With the deformation rate increase the concentration

The influence of high-temperature annealing on absorption spectra of nominally pure and impure MgO crystals irradiated in a nuclear reactor has been investigated. In nominally pure crystals, as a whole, the accumulation of defect aggregates of non-mo

Thermally stimulated luminescence (TSL) of aluminoborosilicate glass doped with CdSe nanoparticles (28 and 47 A) has been studied after exposure to ionizing radiation; the intense TSL peaks were observed at temperatures 150 and 85 °C, respectively.
