AbstractAbstract

[en] Laser-induced time-resolved luminescence, decay times and optical spectroscopy of natural topaz Al₂SiO₄(OH,F)₂ show the presence of several luminescence centers: single Cr³⁺ in intermediate crystal field position, Cr-Cr pairs and radiation induced center. The possible connection of the last center with Mn⁴⁺ and V²⁺ is discussed
