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 ...
Doped zirconia phase and luminescence dependence on the nature of charge compensation
(Nature Publishing Group, 2017)
Zirconia is a relatively new material with many promising practical applications in medical imaging, biolabeling, sensors, and other fields. In this study we have investigated lanthanide and niobium doped zirconia by ...
Colorimetric gas detection by the varying thickness of a thin film of ultrasmall PTSA-coated TiO2 nanoparticles on a Si substrate
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2017)
Colorimetric gas sensing is demonstrated by thin films based on ultrasmall TiO2 nanoparticles (NPs) on Si substrates. The NPs are bound into the film by p-toluenesulfonic acid (PTSA) and the film is made to absorb volatile ...
Tunneling luminescence in long lasting afterglow of SrAl2O4:Eu,Dy
(Elsevier B.V., 2017)
A long lasting (afterglowing) luminescent material SrAl2O4: Eu2+, Dy3+ was prepared by high temperature solid-state reaction method. The processes responsible for long lasting luminescence were studied by means of luminescence ...
Facile synthesis of magnetically separable CoFe2O4/Ag2O/Ag2CO3 nanoheterostructures with high photocatalytic performance under visible light and enhanced stability against photodegradation
(Elsevier Sci Ltd., 2017)
We have developed magnetically separable and reasonably stable visible light active photocatalysts containing CoFe2O4 and mixture of Ag2O/Ag2CO3 nanoheterostructures. Obtained ternary nanoheterostructures outperform ...
Radioluminescence, thermoluminescence and dosimetric properties of ZnO ceramics
(Elsevier Ltd, 2017)
Two types of ZnO ceramics were fabricated and characterized by XRD, SEM methods. The radioluminescence spectra were measured within the 300–550 K range. The defect luminescence band peaking at ~2.35 eV is the dominant one ...
