Abstract
The photoluminescent behaviour of Cr3+ in several materials of commercial o rigin was investigated, and results were compared with those of more usual optical, structural and elemental analysis methods. Some of the above mater ials were identified as defect spinels, belonging to the MgAl2O4-Al2.67O4 ( gamma-alumina). The use of photoluminescence spectroscopy appears specially advisable when samples of unusual shape or size have to be identified.
