Abstract

Abstract: Porous silica glasses of different porous sizes are used as hosts for Eu 3+ -ions from a Eu(NO3 )3 solution. The glasses were subjected to a sintering process in which the porous microstructure collapses. This work is dedicated to the study of the microstructure of sintered glasses containing Eu 3+ ions, through (scanning) transmission electron microscopy ((S)TEM), energy-dispersive X-ray spectroscopy (EDXS), and X-ray diffraction (XRD). The microstructure achieved is strongly dependent on the pore size, heating rate, and sintering temperature. Eu 3+ ions are localized in particles growing in the pores during the sintering.
