Spectroscopic, luminescence and in vitro biological studies of solid ketoprofen of heavier trivalent lanthanides and yttrium(III)
(Elsevier B.V., 2014-11-01)
Solid-state compounds of the general formulae [ML3] (M = Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y; L = ketoprofen) were synthesized and characterized using infrared, diffuse reflectance and luminescence spectroscopies. IR data ...
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), ...

Glyphosate analysis in water samples by luminescence spectroscopy using lanthanides as chromophores
(Universidade Federal de São Paulo, 2022-03-25)
The development of techniques seeking glyphosate’s analysis by analytical methods has been broadly studied for the past years. However, many methods still require expensive resources, making them not so practical. Thus, ...
New chelate complexes of trivalent Y and lanthanides (Eu, Ho, Yb) with a triazene N-oxide: Synthesis, structural characterization and luminescence properties
(Elsevier B.V. Sa, 2011-01-30)
Deprotonated 3-(4-nitrophenyl)-1-phenyltriazene N-oxide reacts with YCl3 center dot 6H(2)O and LnCl(3)center dot 6H(2)O (Ln = Eu, Ho, Yb) to give the monoclinic chelate complexes [Y{O2N(C6H4)NNN(O)Ph}(4)](Et3NH)center dot ...
