Ultrafast core-to-core luminescence in BaF-LaF single crystals
Roman Shendrik, Evgeny Radzhabov, Alexandra Myasnikova +6
This study investigates the mechanisms underlying ultrafast cross-luminescence observed in BaF crystals doped with LaF. We identified an ultrafast luminescent component wit…
Role of electron and hole centers in energy transfer in BaBrI crystals
Roman Shendrik, Alexandra Myasnikova, Alexey Rupasov +1
In this paper we study a role of F-centers, hole centers and excitons in energy transfer in Eu-doped BaBrI crystals. Optical absorption spectra, thermally stimulated (TSL) and phot…
Luminescence of BaBrI and SrBrI single crystals doped with Eu2+
A. A. Shalaev, R. Shendrik, A. Myasnikova +3
The crystal growth procedure and luminescence properties of pure and Eu-doped BaBrI and SrBrI crystals are reported. Emission and excitation spectra were recorded under ultr…
Optical and structural properties of doped BaBrI and BaClI crystals
R. Shendrik, A. Myasnikova, A. Shalaev +4
The work is necessitated by search for new materials to detect ionizing radiation. The rare-earth ions doped with ternary alkali earth-halide systems are promising scintillators sh…
Luminescence of photochromic centers in calcium fluoride crystals doped with Lu ions
Roman Shendrik, Alexandra Myasnikova, Tatiana Sizova +1
We report data on the luminescence spectra associated with photochromic centers in X-ray irradiated calcium fluoride crystals doped with Lu ions. Irradiation in low energy photochr…
Anomalous europium luminescence in LaF3
E A Radzhabov, R Yu Shendrik
Optical spectra (absorption, emission, excitation, decay) and dielectric relaxation were measured for divalent europium (and partially for ytterbium) in lanthanum fluoride crystals…
Instability of some divalent rare earth ions and photochromic effect
A. V. Egranov, T. Yu. Sizova, R. Yu. Shendrik +1
It was shown that the divalent rare earth ions (La, Ce, Gd, Tb, Lu, and Y) in cubic sites in alkaline earth fluorides are unstable with respect to electron autodetachment since its…
Spectroscopy of divalent rare earth ions in fluoride crystals
R. Shendrik, A. S. Myasnikova, E. A. Radzhabov +1
We have studied the absorption spectra of x-ray irradiation-induced Ce2+ and Pr2+ ions in crystals of alkaline-earth fluorides. We have calculated absorption spectra of divalent pr…
Luminescence of cadmium fluoride doped with rare-earth ions
Evgeny Radzhabov, Roman Shendrik
Absorption, excitation and emission spectra of cadmium fluoride crystals doped with rare-earth ions were investigated. In contrast to alkaline-earth fluorides the absorption spectr…
Radiation defects in BaF-Cd
A. V. Egranov
Radiation defects in barium fluoride single crystals doped with cadmium have been investigated by luminescence and absorption spectroscopy, as well as by electron spin resonance sp…
Absolute light yield measurements on SrF and BaF doped with rare earth ions
Roman Shendrik, Evgeny Radzhabov
Results of absolute light output measurements on strontium and barium fluoride doped with PrF and CeF are presented and compared with scintillators having well-known light…
Local structure and defect segregation on the tilt grain boundaries in silicon
Vitaly Yu. Lazebnykh, Andrey S. Mysovsky
We present the results of atomistic and ab initio simulation of several different tilt grain boundaries (GB) in silicon. The boundary structures obtained with genetic algorithm tur…
Scintillation properties of pure and Ce-doped SrF crystals
R. Shendrik, E. A. Radzhabov, A. I. Nepomnyashchikh
In this paper results of scintillation properties measurements of pure and Ce3+-doped strontium fluoride crystals are presented. We measure light output, scintillation decay time p…
Configurational instability at the excited impurity ions in alkaline earth fluorites
Alexander Egranov, Tat'yana Sizova
The formation of intrinsic defects by ionizing radiation in some ionic crystals in the anion sublattice is only associated with the instability of the self-trapped exciton up to no…
