Glasses including quantum dots of cadmium sulfide, silver, and laser dyes

A new type of glases, either totally inorganic or composites of organic and inorganic materials are doped by silver aggregates, photostable organic dyes and semiconductor quantum dots. The experimental technique for preparation of such materials is outlined. Spectroscopic properties of these materials are presented and their application for fiber waveguides, tunable lasers and nonlinear optics materials demonstrated.
