Abstract

The ruby samples were grown by the Czochralski technique. We used as starter materials Al₂ O₃ powder of 99.99% doped with 1% of Cr₂O₃ The monocrystals obtained were clived to form samples of 5X5X2 mm³ size. The X-ray diffraction pattern shows a rhombohedral structure type. The elemental composition was determined by EDS. The samples were irradiated with a power from 0 to 15 KV to observe the different impurities levels of emission and the saturation power. The photoluminescence spectra showed two band at 697 and 772 nm. respectively.
