The X-ray absorption near edge structure (XANES) and X-ray excited optical luminescence (XEOL) of a set of photoluminescent rare earth (RE) (Tb, Ce) doped silicon oxide (SiO x ) thin films, having compositions ranging from O-rich (32% Si) to Si-rich

Silicon nanoclusters (Si-ncs) embedded in silicon nitride films have been studied to determine the effect that deposition and processing parameters have on their growth, luminescent properties, and electronic structure. Luminescence was observed from

The authors have studied photoluminescence (PL) from Er-doped Si-rich Si oxide (SRSO) films deposited by magnetron sputtering of an Er+Si+SiO2 composite target in Ar or Ar+H2 ambients. When the samples were annealed in N2, for the film grown in an Ar

Rare earth (Tb or Ce)-doped silicon oxides were deposited by electron cyclotron resonance plasma-enhanced chemical vapour deposition (ECR-PECVD). Silicon nanocrystals (Si-ncs) were formed in the silicon-rich films during certain annealing processes.

Si nanoclusters embedded in two different dielectric matrices, silicon oxide and silicon nitride, have been formed through annealing of Si-rich silicon oxide (SRSO) and Si-rich silicon nitride (SRSN) thin films. The light emitting properties of these

We have studied photoluminescence (PL) from SiO2 films co- doped with (Er, Ge) deposited by magnetron sputtering of an Er+Ge+SiO2 composite target in pure Ar ambient. Under excitation of a 325 nm He-Cd laser line, blue emission bands around 400 nm an
