Rare earth ions doped materials continue to be the subject of several researches thanks to their efficiency in the fields of photonics and their applications in amplifiers or optical fiber lasers. In this context, firstly, silica bulks (SiO2) doped with europium ions (Eu3+) were prepared by Sol-Gel process. The luminescence properties of rare earth ions were studied in these bulks, as well as in bulks co-doped with magnesium and heat-treated at 900°C. The optical properties of Eu3+ ions have also been studied in a very different environment: silica nanoparticles (NPSi). These different materials were characterized by ICP-OES, TEM, XRD, sorption analysis and FT-IR. The first part of this manuscript describes how the size of the NPSi, the amo...
