Blue light-emitting glasses were successfully prepared by doping Eu 2+ ions in the system Al 2 O 3 –SiO 2 . The Al 2 O 3 –SiO 2 glasses doped with Eu 3+ ions were synthesized using a sol–gel method, followed by heating in hydrogen gas atmosphere to reduce into the Eu 2+ ions. The obtained glasses exhibited emission spectra with...
