Abstract

Visual luminescence of natural margarosanite, swedenborgite and walstromite is well known for mineralogists, but their spectral characteristics and interpretation were still missing. We studied those minerals by laser-induced time-resolved luminescence technique, described the corresponding spectral and kinetic parameters and interpreted the luminescence centers as follows: margarosanite - Mn²⁺, Mn²⁺ clusters, Pb²⁺ and Ce³⁺; swedenborgite - Sb³⁺; walstromite - Mn²⁺, Eu²⁺ and trivalent rare-earth elements.
