Abstract

Luminescence of natural sillimanite Al_(2)SiO_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.
