Paper Abstract

The preparation of organic-inorganic hybrids based on the use of sol-gel chemistry offers a creative approach for synthesizing novel optical materials. Specifically, hybrid materials derived from combining silica and acrylic systems have been shown to be effective host matrices for organic laser dyes. However, the synthesis must be carefully designed in order to retain the beneficial properties of both constituents within a single hybrid network, without compromising optical quality. In this paper, three approaches for initiating polymerization reactions of the organic component are reported. Raman and optical spectroscopies are used to correlate the influence of organic and inorganic network development on optical transparency of the hybrid. The most successful synthesis method involved dissolving the sol components in a common solvent before instituting polymerization treatments. Materials synthesized from this approach satisfy three important criteria for organic- inorganic hybrid layer host materials: an optically transparent matrix with little or no phase separation; equal amounts of organic and inorganic to obtain the benefits of both phases; and a high degree of organic polymerization.
