摘要：

The monolithic silica glass doped with Tb3+ ions was fabricated using the SiO2-PVA nanocomposite as the glass precursor. In order to dope Tb3+ ions in the monolithic silica glass, the mesoporous SiO2-PVA nanocomposite was immersed in the Tb3+ ions contained solution and subsequently sintered at 1100 degrees C in air. Consequently the monolithic transparent silica glass was obtained, exhibiting green fluorescence attributed to D-5(4) -> F-7(5) main transitions under UV excitation. The Tb concentration in the sintered glass could be controlled by immersion time of the nanocomposite in the solution. (C) 2014 Elsevier B.V. All rights reserved.
