Eco-friendly polydimethylsiloxane-based self-supporting film containing europium-polyoxometalate: A flexible luminescent material for white light generation
(Elsevier B.V., 2018-09-01)
Lanthanide (Ln(3+))-doped suitable matrices exhibit unique luminescent properties which are important for applications in optoelectronic devices. Most of the Ln(3+)-based luminescent materials are, however, prepared in ...
Towards carbon monoxide sensors based on europium doped cerium dioxide
(2019-01-15)
Ce 1-(3/4)x Eu x O 2 (x = 0.00 and x = 0.08) thick films were prepared from nanoparticles synthesized by the microwave-assisted hydrothermal route, aiming their application as a carbon monoxide sensing material to prevent ...
Lithium lanthanum titanate perovskite ionic conductor: Influence of europium doping on structural and optical properties
(2018-01-01)
The present study reports the insertion of europium ions into the network of lithium lanthanum titanate, La0.5Li0.5TiO3, powders. The materials were prepared efficiently via the Pechini method and were characterized using ...
Enhanced luminescence of Tb(3+)/Eu(3+) doped tellurium oxide glass containing silver nanostructures
(AMER INST PHYSICS, 2009)
We report on energy transfer studies in terbium (Tb(3+))-europium (Eu(3+)) doped TeO(2)-ZnO-Na(2)O-PbO glass containing silver nanostructures. The samples excitation was made using ultraviolet radiation at 355 nm. Luminescence ...
Characterization, photoluminescence, thermally stimulated luminescence and electron spin resonance studies of Eu(3+) doped LaAlO(3) phosphor
(ELSEVIER SCIENCE BV, 2011)
Europium-doped lanthanum aluminate (LaAlO(3)) powder was prepared by using a combustion method. The crystallization, surface morphology, specific surface area and luminescence properties of the samples have been investigated. ...
Luminescent nanoparticles of MgAl(2)O(4):Eu, Dy prepared by citrate sol-gel method
(ELSEVIER SCIENCE BV, 2008)
MgAl(2)O(4):Eu, Dy nanoparticles were prepared by citrate sol-gel method and thermally treated at 600, 700, 800 and 900 degrees C. The trivalent europium ion is partially reduced to the divalent state at 700 and 800 degrees ...
Novel electroluminescent devices containing Eu(3+)-(2-acyl-1,3-indandionate) complexes with TPPO ligand
(ELSEVIER SCIENCE BV, 2009)
Fabrication and electroluminescent properties of devices containing europium complexes of general formula [Eu(ACIND)(3)(TPPO)(2)], where ACIND, 2-acyl-1,3-indandionate ligands: and TPPO, triphenylphosphine oxide. as emitter ...
Novel polymer electrolytes based on gelatin and ionic liquids
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This study describes the results of the characterization of polymer electrolytes using gelatin matrix doped with europium triflate and/or different ionic liquids. Samples of solvent-free electrolytes were prepared and ...
Enhanced emission from Eu(III) beta-diketone complex combined with ether-type oxygen atoms of di-ureasil organic-inorganic hybrids
(Elsevier B.V., 2003-06-01)
Organic-inorganic hybrids, named di-ureasils and described by polyether-based chains grafted to both ends to a siliceous backbone through urea cross linkages, were used as hosts for incorporation of the well-known coordination ...
Study of Hybrid Silica-Polyethyleneglycol Xerogels by Eu3+ Luminescence Spectroscopy
(1999-12-01)
Good optical quality Eu3+-doped silica-polyethyleneglycol hybrids were prepared by the sol-gel process. Thermomechanical analysis showed an increase of the glass transition temperature, due to the stiffness of the polymeric ...
