Particle size effects on the structure and emission of Eu3+: LaPO4 and EuPO4 phosphors
(Journal of Luminescence, 2018)
This paper provides the detailed study of (nano) particles size effect on structural and luminescent properties of LaPO4: Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ...
Luminescence thermometry with Eu3+ doped GdAlO3
(Elsevier, 2016)
Eu3+ doped GdAlO3 powder synthesized by solid state reaction was investigated for application in luminescence thermometry. Phase composition of material was confirmed by X-ray powder diffraction analysis. The photoluminescence ...
Non-contact thermometry with Dy3+ doped Gd2Ti2O7 nano-powders
(Elsevier, 2016)
The performance of Dy3+ doped Gd2Ti2O7 nano-powders for luminescence temperature sensing was tested over a temperature range from 293 to 443 K. The Dy3+ ions were incorporated into Gd2Ti2O7 nanocrystals using a hydrolytic ...
Fast photoluminescence quenching in thin films of 4,4 -bis(2,2-diphenylvinyl)-1,1 -biphenyl exposed to air
(Journal of Luminescence, 2015)
The photoluminescence (PL) quenching mechanism of UV light and air-exposed amorphous thin films of 4,4-bis(2,2-diphenylvinyl)-1,1-biphenyl (DPVBi), a well-known hole-transport material used in organic light-emitting diodes, ...
Effect of annealing on luminescence of Eu3+- and Sm3+-doped Mg2TiO4 nanoparticles
(Elsevier, 2016)
This work explores the influence of annealing temperature on the structure and luminescence of 2 at% Eu3+ and 1 at Sm3+-doped Mg2TiO4 nanopowders produced via Pechini-type polymerized complex route. Mg2TiO4 samples were ...
PARAFAC: A tool for the analysis of phosphor mixture luminescence
(Elsevier, 2016)
Parallel factor analysis (PARAFAC) was demonstrated as a tool for the analysis of the time-resolved emission spectra of mixtures of rare-earth phosphors. The time-resolved luminescence spectra of mixtures of europium(III)-doped ...
Ratiometric luminescence thermometry with different combinations of emissions from Eu3+ doped Gd2Ti2O7 nanoparticles
(Journal of Luminescence, 2016)
Herein, Eu3+ doped Gd2Ti2O7 nanoparticles were tested for application in ratiometric luminescence thermometry. It is shown that two combinations of emissions: one that uses two emissions of Eu3+ ions and one that uses one ...
Temperature quenching of luminescence emission in Eu3+- and Sm3+-doped YNbO4 powders
(Journal of Luminescence, 2014)
We prepared Eu3+- and Sm3+-doped YNbO4 phosphor powders using a simple solid-state reaction method and examined their photoluminescence properties in order to investigate the possibility for their usage in phosphor ...
Strong emission via up-conversion of Gd2O3:Yb3+, Ho3+ nanopowders co-doped with alkali metals ions
(Journal of Luminescence, 2014)
Gadolinium-oxide nanopowders doped with Yb3+ and Ho3+ ions and co-doped with alkali metal ions (Li+ and Na+) were synthesized via the polymer complex solution method and their up-conversion emission properties are analyzed. ...
Sm3+ doped TiO2 nanoparticles synthesized from nanotubular precursors-luminescent and structural properties
(Journal of Luminescence, 2013)
We report on a new synthetic route for synthesis of Sm3+ doped TiO2 nanocrystals by shape transformation of hydrothermally treated titania nanotubes in the presence of Sm3+ ions. Shape and size of Sm3+ doped TiO2 nanocrystals ...
