Upconversion luminescence from Nd-doped gerimania-ormosil organic–inorganic hybrid films derived at low temperature

Nd-doped germania-ormosil hybrid films are synthesized by a sol–gel spin-coating technique for photonic applications. Acidcatalyzed solutions of c-glycidoxypropyltrimethoxysilane mixed with gemanium isopropoxide are used as matrix precursors. Planar waveguide films with a thickness of about 1.8-lm are obtained by a single spin-coating process and at low temperature heat treatment. The effects o...

Molecular design of hybrid organic-inorganic materials

Hybrid organic-inorganic materials offer a wide range of interesting applications especially in optics. Chemistry plays a major role in the elaboration and comprehension of such materials. Sol-gel process provide a method to blend, down to the molecular scale, organic and inorganic components. Examples of hybrid organic-inorganic materials for optics and optical characterizations of hybrid mate...
