Abstract

Rare earth doped glass-ceramics transparent in the infrared region up to 16 μm have been prepared and studied. The enhancement of the emission of Er3+ ions at 1.54 μm with increasing crystallinity was demonstrated in a selenium-based glass-ceramic having a composition of 80GeSe2-20Ga2Se3 + 1000 ppm Er. The optical transmission, microstructure and luminescence properties of a base glass and glass-ceramics were investigated. Luminescence intensities up to 7 times greater were obtained in glass-ceramics in comparison to the base glass. These materials are promising candidates for the production of new laser sources in the mid-infrared region.
