Afterglow, TL and OSL properties of Mn2+-doped ZnGa2O4 phosphor
(Nature Publishing Group, 2019)
Zinc gallate (ZnGa2O4) spinel ceramics doped with Mn2+ ions was prepared by a solid-state reaction at 1200 °C in air. Manganese concentration was equal to 0.05 mol.% of MnO with respect to ZnO. Ceramics produced in this ...
Computer Simulations of the Band Structure and Density of States of the Linear Chains of NaCl Ions
(Sciendo, 2019)
The paper presents the results of first-principles computer simulations of the band structure, the density of states, and the total energy of NaCl (NaCl, Na2Cl2, Na3Cl3, Na4Cl4, Na6Cl6) linear chains of atoms. Modelling ...
Luminescence Properties and Decay Kinetics of Mn 2+ and Eu 3+ Co-Dopant Ions in MgGa 2 O 4 Ceramics
(Sciendo, 2018)
The MgGa 2 O 4 ceramics co-doped with Mn 2+ and Eu 3+ ions were synthesized via a higherature solid-state reaction technique. The samples with various Eu 3+ concentrations were characterised using high-resolution ...
Systematic trends in (0 0 1) surface ab initio calculations of ABO3 perovskites
(Elsevier B.V., 2018)
By means of the hybrid exchange–correlation functionals, as it is implemented in the CRYSTAL computer code, ab initio calculations for main ABO3 perovskite (0 0 1) surfaces, namely SrTiO3, BaTiO3, PbTiO3, CaTiO3, SrZrO3, ...
Effects of Mn doping on dielectric properties of ferroelectric relaxor PLZT ceramics
(Elsevier B.V., 2017)
A series of PLZT (8/65/35) ceramics with different Mn2O3 concentration (0.01, 0.1, 0.3, 1.0, and 3.0% by weight) have been synthesized to figure out its influence on their dielectric properties. The complex dielectric ...
Accumulation of radiation defects and modification of micromechanical properties under MgO crystal irradiation with swift 132Xe ions
(Elsevier B.V., 2020)
Accumulation of F-type defects under irradiation of MgO crystals by 0.23-GeV 132Xe ions with fluence varying by three orders of magnitude has been investigated via the spectra of optical absorption and low-temperature ...
Peculiarities of the diffusion-controlled radiation defect accumulation kinetics under high fluencies
(Elsevier B.V., 2020)
Theory is developed for kinetics of the diffusion-controlled radiation defect accumulation in crystalline solids under high fluencies taking into account recently observed correlation between the defect diffusion energy ...
Hybrid density functional calculations of hyperfine coupling tensor for hole-type defects in MgAl2O4
(Elsevier B.V., 2020)
We have performed the density functional calculations (DFT) on the hole-type defects (V-centres) in magnesium aluminate spinel (MgAl2O4) following the results of recent paramagnetic resonance measurements (EPR) in Nucl. ...
Ion track template technique for fabrication of ZnSe2O5 nanocrystals
(Elsevier B.V., 2020)
ZnSe2O5 nanocrystals with an orthorhombic structure were synthesized by electrochemical deposition into a-SiO2/n-Si ion track template formed by 200 MeV Xe ion irradiation with the fluence of 107 ions/cm2. The lattice ...
Analysis of self-trapped hole mobility in alkali halides and metal halides
(Elsevier B.V., 2017)
The small radius hole polarons (self-trapped holes (STH) known also as the Vk centers) are very common color centers observed in numerous alkali halides and alkaline-earth halides. Their mobility controls the rate of ...
