Luminescent properties of some rare earth phosphates
(Gordon Breach Sci Publ Ltd, 1996-01-01)
Luminescent properties of scandium and yttrium phosphates are discussed and mechanisms involving their emissions proposed.
Luminescent properties and lattice defects correlation on zinc oxide
(Elsevier B.V., 2001-11-01)
The ZnO luminescent properties are strongly influenced by the preparation method and they are principally related to electronic and crystalline structures. This work reports about the correlation among luminescence properties ...
Luminescent properties of yttrium diphenylphosphinate activated by europium
(Elsevier B.V., 2006-07-20)
The synthesis and spectroscopic characterization of yttrium diphenylphosphinates doped with europium are reported. The purity of all samples was confirmed by carbon and hydrogen micro analysis, thermal analysis, IR vibrational ...
Luminescence and non-radiative processes in lanthanide squarate hydrates
(1996-11-01)
The luminescence properties of solid hydrated lanthanide squarates (Ln2(C4O4)3(H2O) x; x = 8 or 13;Ln3+ = Gd, La, Eu, Tb, Pr) are reported for temperatures down to 4.2K. The luminescence of the squarate group is observed ...
Integrated X-ray crystallography, optical and computational methods in studies of structure and luminescence of new synthesized complexes of lanthanides with ligands derived from 2,6-diformylpyridine
(2011-03-24)
The reaction of 2,6-diformylpyridine-bis(benzoylhydrazone) [dfpbbh] and 2,6-diformylpyridine-bis(4-phenylsemicarbazone) [dfpbpsc] with lanthanides salts yielded the new chelates complexes [Eu(dfpbpsc-H +) 2]NO 3 (1), ...
Luminescent nano-composites generated from a spray
(Elsevier B.V., 2008-11-01)
The spray-pyrolysis (SP) synthesis technique has been employed to obtain SiO2:Eu3+ and gamma-AlOOH:Eu3+, It was possible to obtain sub-micrometric spherical particles of SiO2 with luminescent Eu3+ ions bonded to the silica ...
Nanostructure and luminescent properties of sol-gel derived europium-doped amine functionalised hybrids
(Springer, 2006-02-01)
The effect of doping by europium triflate on the nanoscopic structure of organic-inorganic hybrid formed by a siliceous network containing pendant amine-terminated propyl chains, called aminosils, was investigated by ...
Effects of dispersion by Gd3+ upon europium diphenylphosphinate luminescence
(Elsevier B.V., 2001-07-12)
A series of binary diphenylphosphinates with Eu3+ and Gd3+ were prepared. The compounds have the general formula Gd1-xEux(DPP)(3), where x ranges from 0 to 1. The spectroscopic measurements show interesting behavior. The ...
Incorporation of a liquid crystal to enhance the luminescence properties of Langmuir-Blodgett films of OC1OC6-PPV
(Elsevier B.V., 2009-11-01)
The control of molecular architecture provided by the Langmuir-Blodgett (LB) method allows one to obtain enhanced luminescence properties in polymer films, which can be exploited in polymer light emitting diodes (PLEDs). ...
EXAFS, SAXS and Eu3+ luminescence spectroscopy of sol-gel derived siloxane-polyethyleneoxide hybrids
(Kluwer Academic Publ, 2000-12-01)
Hybrid Eu3+-doped silica-poliethyleneoxide (PEO) nanocomposites with covalent bonds between the inorganic (siloxane) and organic (PEO) phases have been obtained by sol-gel process. These materials are transparent, flexible ...
