Comparison of Luminescence in LiGaO2, Al2 O3 -Ga and Al2 O3 -Li Crystals
(Sciendo, 2018)
We have studied luminescence of LiGaO 2 , Al 2 O 3 -Ga and Al 2 O 3 -Li crystals in order to reveal the nature of luminescence centres and mechanisms in these crystals. In Al 2 O 3 -Ga presence of Ga impurities determines ...
Luminescence of F2 and F3 + centres in LiF crystals irradiated with 12 MeV 12C ions
(Institute of Physics Publishing, 2018)
Dependences of the nanohardness and photoluminescence of F 2 and F 3 + centers on the depth in LiF crystals irradiated with 12 MeV 12 C ions to fluences 10 10 -10 15 ions/cm 2 were studied using laser scanning confocal ...
Local structure of A-atom in ABO3 perovskites studies by RMC-EXAFS
(Elsevier Ltd, 2018)
The ferroelectric distortions in perovskites were a subject of numerous investigations for a long time. However, some controversial results still exist, coming from the analysis of diffraction (X-ray, neutron or electron) ...
Mach-Zehnder interferometer implementation for thermo-optical and Kerr effect study
(Springer Verlag, 2018)
In this paper, we propose the Mach–Zehnder interferometric method for third-order nonlinear optical and thermo-optical studies. Both effects manifest themselves as refractive index dependence on the incident light intensity ...
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 ...
Measurement of Low Concentration of Nanosized Objects Suspended in a Liquid Medium
(De Gruyter Open Ltd, 2018)
The new optical scheme of refractometer with temperature stabilisation 10-2 °C is developed, which allows measuring a refractive index of the sample with accuracy not worse than 10-5; dependence of refraction index on ...
Plasma-wall interaction studies within the EUROfusion consortium: Progress on plasma-facing components development and qualification
(Institute of Physics Publishing, 2018)
The provision of a particle and power exhaust solution which is compatible with first-wall components and edge-plasma conditions is a key area of present-day fusion research and mandatory for a successful operation of ITER ...
Photovoltaic effect in bulk heterojunction system with glass forming indandione derivative DMABI-6Ph
(Elsevier Ltd, 2018)
The aim of the work is to evaluate possible use of 2-[[4-(bis(2-trityloxyethyl)amino)phenyl]methylene]indane-1,3-dione (DMABI-6Ph) as light absorbing material for solar cells. DMABI-6Ph is a perspective material due to its ...
Surface termination effects on the oxygen reduction reaction rate at fuel cell cathodes
(Royal Society of Chemistry, 2018)
The results of first principles calculations of oxygen vacancy and oxygen adsorbate concentrations are analyzed and compared for the polar (La,Sr)O and MnO2 (001) terminations of (La,Sr)MnO3 fuel cell cathode materials. ...
Probing the Thermochromic Phase Transition in CuMoO4 by EXAFS Spectroscopy
(Wiley-VCH Verlag, 2018)
Extended X-ray absorption fine structure (EXAFS) spectroscopy at the Mo K-edge is used to follow the thermochromic γ-to-α phase transition in copper molybdate (CuMoO4). The temperature dependence (10–300 K) of the radial ...
