A full concentration range of Lu2xGd2–2xSiO5 (LGSO:Ce) crystals was grown by the Czochralski method. Dependence scintillation properties on composition (x) in solid solutions is established. It determined that LGSO:Ce yield increases 0.3 < x 0.8 and reaches 29000 phot/MeV at 60% Lu host (x = 0.6), energy resolution improves up to 6.7% 662 KeV. The observed light increase, surprisingly high Ce3+ segregation coefficients, improvement resolution, suppression afterglow can be attributed...
It has been established that for extrapolation of the functional dependence true stresses tensile conditions cylindrical samples metal materials in region large deformations, a power is better suited, where approximation parameters are uniquely determined by standard mechanical characteristics materials. A method proposed calculating ultimate deformations during stretching sample under simultaneous action hydrostatic pressure. shown calculation results satisfactory agreement with known...
Comparative research of the effect low-intensity electromagnetic radiation different ranges on growth Esherichiacoli M-17 was carried out. Certain similarities and differences in effects named radiations studied parameter were revealed.
Composition-property correlations have been systematically studied in the full concentration range of Y3Al5−xGaxO12:Ce (YAGG:Ce) scintillator crystals. The most promising compositions for new high energy physics experiments at colliders determined with light output >200% relative to BGO and fast luminescence decay. Codoping Ca2+ provides decrease phosphorescence intensity 0.2% after 0.6 μs shortening decay constant 21 ns. Factors affecting scintillation time YAGG:Ce discussed. crystals show...
Transparent composite films of polymethylmethacrylate with embedded CsPbBr3 colloidal nanocrystals (CsPbBr3-PMMA) were obtained. The optical, photoluminescent, and scintillation properties the studied. CsPbBr3-PMMA had an intense photoluminescence signal a nanosecond-range decay time (2 ns). characteristics different thicknesses studied upon excitation by α-radiation radionuclides 239Pu (Eα = 5.15 MeV) 238Pu 5.46 MeV). sensitivity minimum detectable activity calculated from pulse-height...
We assess the effectiveness of complementary geophysical techniques to characterize a Jurassic dolomite confined aquifer at Loma de Ubeda, Spain. This aquifer, which is penetrated by wells in 100–600-m depth range, Triassic clays (bottom) and Miocene marls (top). The characterized prominent seismic reflectors high amplitude. Thus, it readily differentiated from low-amplitude confining clay-rich materials. Electrical resistivity tomography (ERT) allowed us detail characteristics up maximum...
Scintillation detectors in the form of luminescent films on a bulk substrate have been developed and explored. Thin doped garnet basis Lu/sub 3/Al/sub 5/O/sub 12/ were grown an undoped Y/sub nonluminescent for application as X-ray imaging screens microtomography. The introduction Lu provided strong absorption X-rays possibility to reduce film thickness down 1 - 2 /spl mu/m achieve spatial resolution 0.8 1.2 mu/m. Doped various materials with adapted path length short-range particles, or...
Radiation defects in β-irradiated Li6Gd(BO3)3:Eu3+ single crystals have been studied by means of thermally stimulated luminescence, radioluminescence, photoluminescence, optical absorption and thermal annealing methods. Parameters traps determined. Models radiation proposed. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
This work has been aimed at measuring the absolute light yield of LGSO:Ce, CWO, ZnSe:Al, and GSO:Ce scintillators in photons/MeV using PMT intrinsic resolution method. Special feature this paper is simultaneous self-consistent determination collection coefficient detector.
Kinetic indentation diagram has been used for the mathematical description of contact interaction between a sphere and elastoplastic half-space. The unloading curve exponent m determined. It shown that value is independent load distribution on surface, does depend ratio c 2 h/R (or h /R). Based deformation characteristics similitude, penetration determined areas constrained developed elastoplasticity. new parameter k (ε y ,n) introduced to account material hardening.
