Luminescence properties of chlorine molecules in glassy SiO2 and optical fibre waveguides
(Estonian Academy Publishers, 2017)
Glassy SiO2 is the basic material for optical fibre waveguides and manufacturing-induced Cl impurities reduce their transparency in UV spectral range. This work reports in-depth study/spectroscopic parameters of the ...
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 ...
Nanoengineered Gd3Al2Ga3O12 Scintillation Materials with Disordered Garnet Structure for Novel Detectors of Ionizing Radiation
(Wiley-VCH Verlag, 2019)
The search for engineering approaches to improve the scintillation properties of Gd3Al2Ga3O12 crystals and enable their production technology is of current interest. This crystal, while doped with Ce, is considered a good ...
Synthesis of Eu2+ and Dy3+ doped strontium aluminates and their properties
(Trans Tech Publications Ltd., 2017)
Strontium aluminate phosphors were synthesized by the solution combustion method using citric acid, urea or glycine as reducing agent and europium and dysprosium as dopants. The content of both dopants was in the range of ...
Photoluminescence and Electron Spin Resonance of ilicon Dioxide Crystal with Rutile Structure (Stishovite)
(Wiley-VCH GmbH, 2018)
An electron spin resonance (ESR) and photoluminescence signal is observed in the as grown single crystal of stishovite indicating the presence of defects in the non‐irradiated sample. The photoluminescence of the as received ...
