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 ...
Effect of in Doping on the ZnO Powders Morphology and Microstructure Evolution of ZnO:In Ceramics as a Material for Scintillators
(Sciendo, 2018)
Transparent ZnO ceramics are of interest for use as material for high-efficiency fast scintillators. Doping ZnO ceramics in order to improve complex of their properties is a promising direction. In the present research, ...
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 ...
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 ...
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 ...
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, ...
Excitation Transfer Engineering in Ce-Doped Oxide Crystalline Scintillators by Codoping with Alkali-Earth Ions
(Wiley-VCH Verlag, 2018)
Time-resolved spectroscopic study of the photoluminescence response to femtosecond pulse excitation and free carrier absorption at different wavelengths, thermally stimulated luminescence measurements and investigation of ...
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 ...
Sub-nanosecond excitonic luminescence in ZnO:In nanocrystals
(Elsevier Ltd, 2019)
The effects of indium concentration influence on the morphology, luminescence spectra and luminescence decay kinetics of ZnO:In nanocrystals prepared by the solar physical vapour deposition method are investigated. While ...
Effect of Ga content on luminescence and defects formation processes in Gd3(Ga,Al)5O12:Ce single crystals
(Elsevier B.V., 2018)
Luminescence characteristics of Ce3+ - doped Gd3GaxAl5-xO12 single crystals with different Ga contents (x = 1, 2, 3, 4, 5) are studied in the 9–500 K temperature range. The spectra of the afterglow, photoluminescence, ...
