摘要：

Eu2+/Dy3+ co-doped high silica glasses with different holding temperatures (T1) and the highest sintering temperatures (T2) were prepared. The emission spectra, infrared absorption spectra, and densities of glass samples show that T1 can greatly influence the shrinkage process of porous glass and 12 decides the residual content of OH groups in sintered samples, which are both important influencing factors on the luminescent properties. The Eu2+/Dy3+ co-doped high silica glass sintered at T1=800 degrees C and T2=1000 degrees C has the highest luminescent intensity for its least residual pores and OH groups. Besides, the theory of pore shrinkage was also referred to explain the experimental results. (C) 2013 Elsevier By. All rights reserved.
