“…Some researchers have also demonstrated the feasibility of optical amplification in the visible range in polymer waveguides doped with ternary Eu III b-diketonates with phen 346,347 or Ln III -Al nanoclusters (Ln = Eu, Tb). [357][358][359] For the latter system the highest optical gain coefficients were estimated to be 0.56 and 1.28 mm À1 for Tb III -Al and Eu III -Al nanoclusters, respectively.…”

Recent startling interest for lanthanide luminescence is stimulated by the continuously expanding need for luminescent materials meeting the stringent requirements of telecommunication, lighting, electroluminescent devices, (bio-)analytical sensors and bio-imaging set-ups. This critical review describes the latest developments in (i) the sensitization of near-infrared luminescence, (ii) "soft" luminescent materials (liquid crystals, ionic liquids, ionogels), (iii) electroluminescent materials for organic light emitting diodes, with emphasis on white light generation, and (iv) applications in luminescent bio-sensing and bio-imaging based on time-resolved detection and multiphoton excitation (500 references).

“…The attenuation loss of the graded index PMMA fiber doped with [Eu(hfac) 3 ] was found to be 0.4 dB/m around 650 nm. Mataki et al fabricated planar polymer optical waveguides from PMMA doped with Eu−Al nanoclusters . Optical amplification was successfully demonstrated at a wavelength of 614 nm under both pulsed operation using a N 2 laser (λ = 337 nm) and CW operation using a frequency-doubled diode-pumped Nd:YAG laser (λ = 532 nm).…”

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.

“…Aluminum-phosphate hybrid sol–gel materials are promising candidates for the fabrication of active optical components due to prompt complexation of lanthanide ions by phosphate species, which is explored in numerous lanthanide phosphate syntheses. , This feature offers the possibility of immobilizing the rare-earth ion in a low-phonon-energy chemical environment, improving its luminescent properties in the near-infrared regime without relying on high-residue-generating approaches such as nanoparticles synthesis , or expensive fluorinated ligands for organometallic complex synthesis . However, these materials are little explored because of their poor gel-forming ability and tendency to precipitate. − Such compositions are commonly used for the synthesis of metal–organic-frameworks (MOFs), due to their fast heterocondensation and limited homo-condensation (both Al–O–Al and P–O–P), , yielding highly ordered structures.…”

In this paper, we report the synthesis and structural characterization of transparent and photopolymerizable aluminum-phosphate-silicate hybrid materials obtained via the sol–gel route, with different aluminum/phosphate (Al/P) ratios. We explored the system Si(1–x)–(Al/P) (x) with x varying from 0.3 to 1, and atomic ratios of Al/P are 1:3, 1:1, and 3:1. All compositions contain high inorganic mass content (up to 40 wt %). Furthermore, they are compatible with vat-photopolymerization platforms. The structural evolution of the hybrid materials with the silicon concentration was investigated by SEM, phase-contrast AFM, and solid-state NMR techniques, using single- and double-resonance experiments. The structure follows the build-up principle using aluminum-phosphate species and alkoxysilane chains as fundamental building blocks. These aluminum-phosphate species were identified as monomeric and dimeric chain structures by comparing different parameters obtained from NMR data to compound models. Monomeric and dimeric aluminum-phosphate chain structures were predominant in 3:1 and 1:3 Al/P ratio samples, respectively, promoting and hindering the heterocondensation with the alkoxysilane precursor, respectively. The photopolymerization mechanism leads to the percolation of the inorganic networks through a parallel polymethylmethacrylate network, resulting in a material with structural heterogeneities in the range of 5 nm, evidenced by phase-contrast AFM.
