Abstract
Luminescence of natural sillimanite Al 2SiO 5 was studied by a laser-induced time-resolved technique combined with absorption spectroscopy. It was found that two red broad emission bands are connected to Fe 3 and Cr 3 luminescence centers. Chromium participation in luminescence was proved by the study of synthetic sillimanite activated by Cr. Several narrow emission lines have been found which were preliminary ascribed to Mn 4 and V 2 luminescence centers.
