摘要：
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.
