Optical and structural properties of Si nanocrystals (Si-nc) in silica films are described. For
the SiO x (x< 2) films annealed above 1000° C, the Raman signal of Si-nc and the …

Interstellar grains span a wide range of sizes from a few angstroms to a few micrometers.
The presence of nanometer-sized or smaller particles in the interstellar medium is indicated …

Optical properties of isolated silicon nanocrystals (nc-Si) with a mean size of∼ 4 nm
embedded in a SiO 2 matrix that was synthesized with an ion beam technique have been …

The photon absorption in Si quantum dots (QDs) embedded in SiO 2 has been
systematically investigated by varying several parameters of the QD synthesis. Plasma …

This contribution is a review of the luminescence and scintillation properties of nanoparticles
(NP), particularly doped insulators. Luminescence spectroscopy is an appropriate tool to …

Authored by leading experts from around the world, the three-volume Handbook of
Nanostructured Thin Films and Coatings gives scientific researchers and product engineers …

An optical study based on spectroscopic ellipsometry, performed on ultrathin hydrogenated
amorphous silicon (a-Si: H) layers, is presented in this work. Ultrathin layers of intrinsic …

We investigated a double silicon-carbide p-layer structure consisting of a undiluted p-type
amorphous silicon-carbide (pa-SiC: H) window layer and a hydrogen diluted pa-SiC: H …

We present evidence for quantum confinement effects on optical transitions in ensembles of
Si nanocrystals (NCs) in a SiO 2 matrix by considering simultaneously the dielectric function …

We report on the effects of high hydrogen dilution on the optical (refractive index, absorption
coefficient and band gap) and electrical (carrier concentration, Hall mobility and dark …
