UV laser photofabrication of waveguide couplers using self-patterning organic-inorganic hybrids
(2011)
Planar waveguides with controlled refractive index were produced using thin films of sol-gel derived organic-inorganic hybrids, so called di-ureasils. Spectroscopic ellipsometry was used to characterize the films thickness ...
Distributed feedback multipeak laser emission in Rhodamine 6G doped organic-inorganic hybrids
(Springer, 2006-12-01)
Organic-inorganic hybrid materials were prepared from an ureasil precursor (ureapropyltriethoxysilane designated as UPTES) and acrylic acid modified zirconium (IV) n-propoxide. Thin films containing rhodamine 6G (Rh6G) ...
Eu3+ doped polyphosphate-aminosilane organic-inorganic hybrids
(Elsevier B.V., 2004-07-14)
The preparation and characterization of new Eu3+ doped polyphosphate-aminosilane hybrids xerogels is reported. Eu3+ D-5(0) emission quantum efficiency ranges from 0.41 to 0.54 depending on the SUP ratio. These rather high ...

Waveguide features in self-patternable amine functionalized organic-inorganic hybrids
(2007-12-01)
We report the use of organic-inorganic sol-gel derived poly(oxyehylene)/ siloxane hybrid doped with methacrylic acid modified zirconium (IV) n-propoxide for the fabrication of low cost waveguides trough direct UV laser ...

Temperature-Independent Polarization of Ultrathin Phthalocyanine-Based Hybrid Organic/Inorganic Heterojunctions
(2020-07-01)
The combination of organic and inorganic materials at the nanoscale to form functional hybrid structures is a powerful strategy to develop novel electronic devices. The knowledge on semiconductor thin-film polarization ...
Depth sensing indentation of organic-inorganic hybrid coatings deposited onto a polymeric substrate
(Elsevier Science Sa, 2012-09-03)
PEO-Si/SiO2 hybrid coatings deposited onto a PVC substrate were micromechanically characterized using depth sensing indentation. The effect of curing time and coating thickness was investigated. Elastic moduli of coated ...
Synthesis of polymeric organic-inorganic hybrid materials. Partially deacetylated chitin-silica hybrid
(Wiley-VCH Verlag, 1997)
This work reports the synthesis of a novel polymeric organic-inorganic hybrid. The inorganic component is a silica network obtained by controlled hydrolysis of tetraethyl orthosilicate via sol-gel process and the organic ...
Hybrid organic-inorganic nanocomposites based on poly(hydroxyethyl methacrylate)/ silica (PHEMA/SIO2)
(European Centre for Nanostructured Polymers, 2013-01)
Hybrid organic-inorganic nanocomposites were prepared through the simultaneous polymerization of 2-hydroxyethyl methacrylate and tetraethoxysilane (TEOS) by the sol-gel process. The resulting PHEMA/SiO2 films (~ 1.5 mm ...
