“…On the other hand, stability study in temperature and under UV irradiation showed larger thermal and photochemical degradation compared with the systems with lower organic content. Similar studies have been conducted involving Eu 2 [TeMo 6 O 24 ] and [EuW 10 O 36 ] 9À anions and the resulting materials showed enhanced emission intensity and luminescence quantum yield compared with the corresponding POM in solution [51,52].…”

“…815 The first examples of lanthanide-containing polyoxometalate complexes in sol-gel glasses were described by Lis, Klonkowksi, and co-workers. 773,816 456 Not only the compositional parameter x but also the composition of the ormosil matrix were found to have an effect on the photophysical properties. The highest luminescence intensity was observed for K 13 [Eu(SiMoW 10 O 39 ) 2 ] doped in a hybrid matrix derived from 3-glycidoxypropyltrimethoxysilane.…”

“…Antonietti and co-workers described the encapsulation of polyoxometalate complexes in a sol−gel silica matrix by blending . The first examples of lanthanide-containing polyoxometalate complexes in sol−gel glasses were described by Lis, Klonkowksi, and co-workers. , The complexes Na 9 [EuW 10 O 36 ] and Eu 2 TeMo 6 O 24 were incorporated in SiO 2 glass and in hybrid materials derived from TMOS and polydimethylsiloxane, and tri(ethylene glycol). The best luminescence performance was observed for Na 9 [EuW 10 O 36 ] in the silica−polydimethylsiloxane hybrids.…”

Koen Binnemans was born in Geel, Belgium, in 1970. He obtained his M. Sc. degree (1992) and Ph.D. degree (1996) in Chemistry at the Catholic University of Leuven, under the supervision of Prof. C. Go ¨rller-Walrand. In the period 1999-2005, he was a postdoctoral fellow of the Fund for Scientific Research Flanders (Belgium). He did postdoctoral work with Prof. Jacques Lucas (Rennes, France) and Prof. Duncan W. Bruce (Exeter, U.K.). In 2000, he received the first ERES Junior Award (ERES, European Rare-Earth and Actinide Society). From 2002 until 2005, he was (parttime) associate professor. Presently, he is professor of chemistry at the Catholic University of Leuven. His current research interests are metalcontaining liquid crystals (metallomesogens), lanthanide-mediated organic reactions, lanthanide spectroscopy, luminescent molecular materials, and ionic liquids.

“…Since such materials based on the antenna effect in Eu(III) complexes are excited by UV radiation, consequently, the relatively high-energy UV quanta are able to decompose photochemically organic groups in an antenna system, especially with organic coligands [20][21][22]. It is why we turn our attention on inorganic systems consisting of Ln(III) complexes in HPOA [23]. Such systems are much more stable during exposition on UV radiation in a long time period than the Ln(III) complex systems with organic ligands.…”
