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 ...
Electronic processes in doped ZnO nanopowders
(Institute of Physics Publishing, 2019)
ZnO nanocrystals, undoped and doped with Iridium or Indium were prepared by solar irradiation in Heliotron reactor in PROMES CNRS facilities, France. The comparative analysis of the excitonic spectra of ZnO single crystal ...
Thermostimulated luminescence of plasma electrolytic oxidation coatings on 6082 aluminium surface
(Elsevier Ltd, 2019)
For decades, plasma electrolytic oxidation (PEO) coatings are actively studied and applied to protect the surface of various valve metals from chemical or mechanical damage. However, over the last couple of years intense ...
Production of Phosphorescent Coatings on 6082 Aluminum Using Sr0.95Eu0.02Dy0.03Al2O4-δ Powder and Plasma Electrolytic Oxidation
(MDPI AG, 2019)
In this study, a new approach for producing phosphorescent aluminum coatings was studied. Using the plasma electrolytic oxidation (PEO) process, a porous oxide coating was produced on the Al6082 aluminum alloy substrate. ...
Novel method of phosphorescent strontium aluminate coating preparation on aluminum
(Elsevier Ltd, 2018)
This study presents a novel approach to produce phosphorescent coatings on metal surfaces. Strontium aluminates are the most popular modern phosphorescent materials exhibiting long afterglow at room temperature and a broad ...
The search for defects in undoped SrAl2O4 material
(Elsevier B.V., 2019)
SrAl2O4:Eu,Dy is a very efficient long afterglow phosphor with wide range of possible applications. The luminescence properties and the possible luminescence mechanism of this material have been studied extensively, but ...
X-ray excited luminescence of SrAl2O4:Eu,Dy at low temperatures
(Elsevier B.V., 2018)
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 ...
Recent progress in understanding the persistent luminescence in SrAl2O4:Eu,Dy
(Taylor and Francis Ltd., 2019)
Ever since the discovery of SrAl2O4:Eu,Dy persistent afterglow material, that can intensively glow up to 20 h, the mechanism of long-lasting luminescence has been a popular area of research. The research is focused on ...
Magnetron sputtering fabrication of α-Al2O3:Cr powders and their T thermoluminescence properties
(Elsevier B.V., 2018)
For many years doped α-Al2O3 has attracted interest as a dosimeter for personal, environment monitoring and food control. The alumina single crystal growth is a difficult process; however, materials in form of powders, ...
