Abstract

Aluminum-lanthanum-silicate glasses with different Eu doping concentration have been synthesized by conventional melt-quenching method at 1680°C in reductive atmosphere. Under 395nm excitation, samples with low Eu doping concentration show mainly the cyan broad emission at 460nm due to 4f65d1-4f7 transition of Eu2+; and the samples with higher Eu doping concentration show mainly some narrow emissions with maximum at 616nm due to 5D0-7FJ (J=0, 1, 2, 3, 4) transitions of Eu3+. Cyan-white-red tunable luminescence under 395nm excitation has been obtained by changing the Eu doping concentration.
