Fabrication and Spectroscopic Properties of (Ho0.01La0.10Y0.89)2O3 Transparent Ceramics

Abstract

Highly transparent (Ho0.01La0.10Y0.89)2O3 transparent ceramics were fabricated by the conventional ceramics processing with nanopowders. The microstructure, the optical properties and the spectroscopic properties of (Ho0.01La0.10Y0.89)2O3 ceramics were investigated. (Ho0.01La0.10Y0.89)2O3 ceramics with the grain size of ~50 μm were obtained by sintering at 1530 °C for 45 h. The highest in-line transmittance reaches 65%. The emission peak located at 2 μm wavelength indicates (Ho0.01La0.10Y0.89)2O3 transparent ceramics is suitable for 2 μm laser gain medium.
