Abstract: We described an improved solgel process to prepare pyridinephenol ligand ((dppy)BF) doped silica composie glass. The addition of Li2CO3 to neutralize the composite sol and solvent extraction with cyclohexane shorten the processing time from several weeks for traditional solgel process to several days. The crackfree (dppy)BF doped silica composite glass with the low volume shrinkage can be obtained by this process. The results of fluorescence spectra indicate that fluorescence intensity of (dppy)BF in the glass enhances, and the photostability is much better.

Key words: pyridinephenol ligand ((dppy)BF), solgel, composite glass
