Sb. Meshkova et al., Enhancement of the luminescence of europium(III) beta-diketonates in the ligand series beta-diketones-their unsaturated analogues-copolymers, J ANALYT CH, 55(7), 2000, pp. 676-681
A change in the luminescence intensity of europium compounds was studied fo
r the series of ligands beta-diketones-their unsaturated analogues (monomer
s)-copolymers with styrene (methyl methacrylate). The optimal ratios of com
onomers (1 : 2; 1 : 5) providing the maximum luminescence intensity of euro
pium were determined. Europium (n x 10(-3)%) was determined in Ce, Pr, Nd,
and Ho oxides, which are strong luminescence quenchers, using copolymers co
ntaining trifluoroacetylacetone and benzoylacetone.
