Luminescence Behavior

ABSTRACTThe narrow, intense emission bands of europium(III) make its compounds of interest for various optical source applications. Previous studies have shown that europium thenoyltrifluoroacetonate complexes, e.g. Eu(TTFA)3, have superior fluorescence properties in select media with respect to inorganic salts like EuCl3. It has been shown that such complexes may be incorporated into solid-state matrices via the sol-gel process. The present research examines the luminescence behavior of a metalorganic complex (Eu(TTFA)3) doped into a sol-gel derived silica-acrylate ORMOSIL host and extends our earlier work on doped silica gel materials. The present study focuses on the effects of dopant concentration and dopant-matrix interaction, and seeks to compare the behavior of Eu(ITFA)3 in silica and ORMOSIL gel host materials.

Luminescence Behavior

A ternary Eu(III) complex with salicylic acid (Hsal) ando-phenanthroline (phen) was synthesized and then incorporated into silica matrix by sol-gel method. The luminescence behavior of the complex in silica gel was studied compared with that of the pure complex by means of emission, excitation spectra and thermogravimetic analysis. The results indicate that the complex Eu(sal)3(phen) in silica gel shows fewer emission lines than pure Eu(sal)3(phen) and the luminescence intensity ratio of the5D0→7F2transition to the5D0→7F1transition is lower than that of the latter. The thermal stability of Eu(sal)3(phen) is enhanced greatly through the introduction of the complex into silica matrix.
