摘要：

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. It was found from absorption spectra 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.
