Abstract

Abstract : Transparent and colorless CeO2 ‐activated borogermanate glasses, with the nominal molar composition of 25B2 O3 –40GeO2 –14Gd2 O3 –1CeO2 –(20− x ) BaO– x BaF2 ( x = 0, 2.5, 5, 10, 15 and 20), were synthesized by a melt‐quenching method in air. Their optical investigation on the transmittance, photoluminescence (excitation and emission spectra), the luminescence decay curves, as well as the temperature‐dependent Ce 3+ emission are studied systematically with the gradual substitution of BaF2 for BaO. The room‐temperature photoluminescence results reveal that the emission intensity can be improved by about 2.5 times with the full substitution of BaF2 for BaO. The blue shift of the cut‐off edge, excitation and emission spectra of Ce 3+ ‐activated borogermanate glass, and the emission intensity of Ce 3+ ions as a function of temperature range in 80–500 K are also discussed.
