摘要：

We studied the optical properties of three organic dyes (Rhodamine 590, DODCI and IR5) incorporated in sol-gel prepared silica glasses. Absorption and emission spectra and luminescence lifetimes were measured both for as-prepared and for heat-densified samples. The blue shift of the emission peak and the radiative lifetimes increase with the densification of the samples.
