The solgel process is a solution synthesis technique which provides a low temperature chemical route for the preparation of rigid transparent matrix materials. Luminescent organic dye molecules have been incorporated via the solgel method into organically modified silicate (ORMOSIL) polymer host matrices. Optical gain, laser oscillation, and photostability of rhodamine and coumarin dyes doped into ORMOSIL gels are reported. The gel laser materials exhibit peak gain values of 40 cm(-1) and show improved photostability with respect to comparable polymeric host materials.
溶胶 - 凝胶法是一种溶液合成技术，它为制备刚性透明基质材料提供了一条低温化学途径。发光有机染料分子已通过溶胶 - 凝胶法被引入到有机改性硅酸盐（ORMOSIL）聚合物主体基质中。报道了掺杂到ORMOSIL凝胶中的罗丹明和香豆素染料的光学增益、激光振荡和光稳定性。凝胶激光材料表现出40 cm⁻¹的峰值增益值，并且相对于可比的聚合物主体材料显示出改善的光稳定性。
