Spectroscopic properties of polycarbonate and poly(methyl methacrylate) blends doped with europium (III) acetylacetonate

A novel scheme to obtain tunable fluorescent colors based on electrospun composite nanofibers

“…Obviously, the fluorescence lifetime of Eu 3+ ions in [10 %Eu(BA) 3 phen + x %Tb(BA) 3 phen]/PVP composite nanofibers is extended gradually, while that of Tb 3+ ions is decreased slowly with increase of Tb (BA) 3 phen content. Similar conclusions about polymers doped by RE complexes can be found in literatures [32,33]. On one hand, The relative content of Eu(BA) 3 phen complexes in the composite nanofibers is reduced with introducing more Tb(BA) 3 phen.…”

Temperature dependence of the luminescence lifetime of a europium complex immobilized in different polymer matrices

“…Lenaerts et al have shown that the luminescence lifetime of EuTTA dihydrate complex in sol-gel matrix is increased by the replacement of water molecules by 1,10-phenanthroline [14]. Bonzanini et al also have observed increased lifetimes for polymers doped with europium b-diketonate complexes [15]. Water molecules are substituted by heterocyclic organic ligands to yield higher quantum yields and lifetimes compared to the hydrated complex [17].…”

Solvent effect on optical properties of hydrated lanthanide tris-acetylacetone

“…In recent decades, lanthanide tris-b-diketones have been receiving much attention because of their bright optical properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] in visible region. Lanthanide tris-bdiketones are of particular interest, since some of them possess bright luminescence (Eu(III) and Tb(III)) in visible region due to radiative 4f-4f transitions of the Ln(III) ion in solution as well as in solid state at room temperature [6][7][8][9][10][11][12][13][14].…”
