Abstract: Using sol-gel techniques, an optical gain medium has been fabricated comprising a glass ceramic host material that includes clusters of crystalline oxide material, especially tin oxide, and that is doped with active ions concentrated at the clusters. The active ions are preferentially located at the nanoclusters so that they experience the relatively low phonon energy of the oxide and are insensitive to the phonon energy of the host. A host with a high phonon energy, such as silica, can therefore be used without the usual drawback of reduced carrier lifetimes through enhanced nonradiative decay rates.

Abstract translation: 使用溶胶 - 凝胶技术，已经制造了包括玻璃陶瓷主体材料的光学增益介质，该玻璃陶瓷主体材料包括结晶氧化物材料簇，特别是氧化锡簇，并且掺杂有集中在簇处的活性离子。 活性离子优先位于纳米团簇上，使得它们经历氧化物的相对低的声子能量，并且对主体的声子能量不敏感。 因此，可以使用具有高声子能量的主体，例如二氧化硅，而没有通过增强的非辐射衰减速率降低载流子寿命的常见缺点。
