Abstract

Eu2+ ions were incorporated into SiO2-BaMgF 4 glass-ceramic thin films using a sol-gel method. The addition of N,N-dimethylformamide to a starting solution resulted in a porous microstructure of the film prepared. The films exhibited blue emission peaking at 420 nm by excitation at 290 nm. The emission was effectively enhanced in the porous film owing to scattering absorption of the excitation light.
