Enhancement of RE ions emission by silica glass nanostructuring
Original language description
Silicate-based glass represents an established material for the fabrication of lasers and amplifiers thanks to excellent material properties, such as thermal stability, mechanical and chemical resistance, as well as low cost and feasible mass-scale fabrication. However, the silica network represents an unsuitable environment for RE ions. The RE ions act as network modifiers, which primarily form ionic bonds with non-bonding oxides in the silica network. In pure silica glass, the RE ions tend to form clusters, which leads to concentration quenching. Additionally, the high phonon energy of silica lattice is responsible for high rates of multiphonon relaxation. To remediate these drawbacks, various strategies were proposed and explored in the past decades. One of these strategies is the modification of the glass network, i.e., nanostructuring of the glass matrix by metal nanoparticles or by oxidic nanoparticles, where the RE is part of a single crystalline nanoparticle and the associated technological conditions in the preparation of the optical fiber. This contribution presents an overview of recent advances in preparation of various metallic or oxidic nanoparticles in silicate glass matrix and the effect on RE ion emission
