OPTICAL CHARACTERISTICS OF Al2O3 CERAMICS DOPED WITH Cr AT HIGH CONCENTRATIONS PREPARED BY EXTRUSION MOLDING PROCESS

Polycrystalline Al2O3 ceramics doped with Cr (sintered ruby) up to high concentrations (0.66, 0.76, and 0.97 wt%) were fabricated with an extrusion molding process using Al2O3 and Cr2O3 powders. Absorption spectra showed that a high concentration of Cr ions was optically activated. The fluorescence...

Summary:Polycrystalline Al2O3 ceramics doped with Cr (sintered ruby) up to high concentrations (0.66, 0.76, and 0.97 wt%) were fabricated with an extrusion molding process using Al2O3 and Cr2O3 powders. Absorption spectra showed that a high concentration of Cr ions was optically activated. The fluorescence spectrum of Cr ions in the sintered ruby corresponded to that of a single crystal. 8 refs.
