摘要：

Europium ions were doped in silica glass matrix with a sol-gel method as well as Al co-dopant. The samples densified at 1050 degrees C showed bright blue emission under UV illuminations. Lifetime of the luminescence was about 1 mu s and did not depend on Al concentration, indicating that europium existed as divalent form at proximate positions to aluminum ions.
