Functional hybrids are nanocomposite materials lying at the interface of organic and inorganic realms, whose high versatility offers a wide range of possibilities to elaborate tailor‐made materials in terms of chemical and physical properties. Because they present several advantages for designing materials for optical applications (versatile and relatively facile chemistry, easy shaping and patterning, materials having good mechanical integrity and excellent optical quality), numerous silica or/and siloxane based hybrid organic–inorganic materials have been developed in the past few years. The most striking examples of functional hybrids exhibiting emission properties (solid‐state dye lasers, rare‐earth doped hybrids, electroluminescent devices), absorption properties (photochromic), nonlinear optical (NLO) properties (second‐order NLO properties, photochemical hole burning (PHB), photorefractivity), and sensing are summarized in this review.

“…This behaviour disagrees with the usual trends measured in volume phase holograms, where the saturation of the eciency is observed after completion of the reactions. 25 These dierences can be explained by the mechanism of grating formation and the variation in ®lm absorption with irradiation time (Fig. 6(b)).…”

This paper describes the properties of some new organic–inorganic photochromic layers. They are based on a hybrid organic–inorganic matrix in which tungsten heteropolyoxometallates (SiW12O4−40, PW12O3−40) are entrapped in a network obtained from the reaction of 3‐glycidoxy‐propyltrimethoxysilane. The high homogeneity of these materials on the nanoscale leads to transparent monoliths and layers of controlled thicknesses up to 40 μm. The optical properties of the blend are emphasised and the construction of amplitude gratings in the materials by two‐wave‐mixing experiments is described. The results of the optical experiments and the comparison with the theoretical background are used as a model for photochromic holographic storage processes. © 1997 John Wiley & Sons, Ltd.

“…Furthermore, the refractive index difference between the nanoparticles and the matrix should be as large as possible. DDDMA and prehydrolyzed (half stoichiometric) MPTS were consequently chosen as matrix components [25,28,[30][31][32][33][34][35][36][37][38]. Before the addition of the Zr-sol, the matrix had to be evaporated by means of a rotation evaporator.…”
