Portable low-cost open-source wireless spectrophotometer for fast and reliable measurements
(Elsevier Ltd, 2020)
We demonstrate a low-cost standalone portable spectrophotometer for fast and reliable measurement execution. The data acquired can be both displayed via a dedicated smartphone application or a computer interface, allowing ...
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 ...
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)
High resolution luminescence spectroscopy and thermoluminescence of different size LaPO4:Eu3+ nanoparticles
(Elsevier B.V., 2018)
Nanoparticles (5 nm) and nanorods (2 nm × 15 nm and 4 nm × 20 nm) of monoclinic monazite LaPO4:Eu3+ were prepared by reverse micelle and co-precipitation techniques. Effects of the particle size and surface defects on the ...
Niobium enhanced europium ion luminescence in hafnia nanocrystals
(Elsevier B.V., 2018)
In this work we demonstrate a method where by adding Nb ions, Ln3+ ion luminescence intensity in HfO2 is increased for up to 15 times (in a sample containing 5 mol%Eu). The effect is described as niobium acting as a charge ...
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 ...
