- Abstract
The luminescence, absorption and circular dichroism spectra of langasite family crystals LaGa-SiO and SrGaGeO doped with chromium ions (0.1 at %) are studied in the region of 300-1200 nm. It is demonstrated that these spectra contain bands typical of both a Cr ion in an octahedral environment (position 1a) and a Cr ion in a tetrahedral site (position 2d). The intensities of these bands differ considerably.
