Formation of dislocations in LiF irradiated with 3He and 4He ions
(Elsevier B.V., 2018)
Influence of the irradiation with 13.5 MeV 3He and 5 MeV 4He ions on the micro-structure and mechanical properties of LiF single crystals was studied. The depth profiles of nanoindentation, dislocation mobility, selective ...
Depth profiles of damage creation and hardening in MgO irradiated with GeV heavy ions
(Elsevier B.V., 2019)
The effect of irradiation with GeV heavy ions (U, Au, Bi) on the structure and mechanical properties of MgO single crystals was studied. The methods of nanoindentation, dislocation mobility, optical absorption and ...
Depth profiles of aggregate centers and nanodefects in LiF crystals irradiated with 34 MeV 84Kr, 56 MeV 40Ar and 12 MeV 12C ions
(Elsevier B.V., 2018)
Depth profiles of nanohardness and photoluminescence of F2 and F3 + centers in LiF crystals irradiated with 12 MeV 12C, 56 MeV 40Ar and 34 MeV 84Kr ions at fluences 1010–1015 ions/cm2 have been studied using laser scanning ...
Phase stability and oxygen-sensitive photoluminescence of ZrO2:Eu,Nb nanopowders
(Elsevier B.V., 2018)
We studied structure and oxygen-sensitive photoluminescence (PL) of ZrO2:Eu,Nb nanocrystalline powders synthesized via a sol-gel route and heat-treated up to 1200 °C. The material containing only 2 at% Eu3+ was predominantly ...
Photoconductivity & photoelectron emission of LiGaO2 crystal excited in intrinsic absorption range
(Elsevier B.V., 2019)
The photoelectric response spectra were studied in a LiGaO2 crystal. The obtained spectra were interpreted as the release and diffusion of charge carriers, as well as external photoemission of electrons. The charge carrier ...
Synthesis and luminescent properties of Mn-doped alpha-tricalcium phosphate
(Elsevier, 2021)
In this work, a series of Mn2+-doped α-tricalcium phosphate (α-TCP) powders was synthesized by wet co-precipitation method followed by high-temperature annealing and thermal quenching. It was shown that Mn2+-doped α-TCP ...
Study of phase composition, photocatalytic activity, and photoluminescence of TiO2 with Eu additive produced by the extraction-pyrolytic method
(Elsevier, 2021)
Due to the unique properties and wide array of applications of nanocrystalline materials based on titanium dioxide, the study of new synthesis approaches remains relevant. In this study, within the framework of the ...
UV light induced processes in pure and doped AlN ceramics
(Elsevier, 2021)
AlN ceramics samples, pure and doped with Y2O3, Eu2O3 and GaN, and produced from the same AlN powder, were studied for photoelectric effect, photoluminescence spectra and kinetics and thermoluminescence under irradiation ...
Electronic Band Transitions in γ-Ge3N4
(Korean Institute of Metals and Materials, 2021)
Electronic band structure in germanium nitride having spinel structure, γ-Ge3N4, was examined using two spectroscopic techniques, cathodoluminescence and synchrotron-based photoluminescence. The sample purity was confirmed ...
Low processing temperatures explored in Sb2S3 solar cells by close-spaced sublimation and analysis of bulk and interface related defects
(Elsevier, 2023)
Antimony trisulfide (Sb2S3) is a promising photovoltaic absorber, which has so far been fabricated mainly by chemical deposition methods. Despite its aptness for congruent sublimation, less research efforts have been made ...
