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.

Abstract
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.File in questo prodotto:
