Abstract

Glasses with compositions ( 100 x ) Si O 2 x Hf O 2 : 0.3 Eu 3 + (molar ratio, x = 0 , 10 , 20 , 30 ) for optical applications were prepared using the sol-gel route. The introduction of hafnium into the glass matrix induced the energy splitting of the F 2 7 state of Eu 3 + ions. Furthermore, fluorescence line narrowing (FLN) spectra indicated that Eu 3 + clustering occurred in glasses containing no hafnium. The addition of hafnium promoted better dispersion of Eu 3 + ions in the glass matrix. The role of hafnium on modifying the properties of glasses was discussed with respect to x-ray diffraction and FLN analysis.
