Europium-Doped Sol-Gel SiO2-Based Glasses: Effect of the Europium Source and Content, Magnesium Addition and Thermal Treatment on Their Photoluminescence Properties

Autor: Hussein Fneich, Nathalie Gaumer, Stéphane Chaussedent, Wilfried Blanc, Ahmad Mehdi

Publikováno v: Molecules, Vol 23, Iss 7, p 1768 (2018)

Rare-earth doped silica-based glasses lead the optical materials due to their tailorable spectroscopic and optical properties. In this context, we took advantage of the sol-gel process to prepare various Eu-doped silica glasses to study their lumines
