Abstract
The work is devoted to obtaining of transparent nanocomposite materials as low loss, highly thermally conductive materials for potential laser applications. We report Ho3+:Y2O3–MgO nanocomposite ceramics with excellent mechanical and optical properties by combining glycine-nitrate process and spark plasma sintering. Morphology, structural-phase state, infrared transmittance and luminescence depending on the holmium concentration (0…12 at.%) were studied for the first time. It was found that optical transmittance reaches 75% at 6000 nm for 3 at.% Ho3+:Y2O3–MgO ceramics.
