Laser-induced time-resolved luminescence of natural margarosanite Pb(Ca,Mn)2Si3O9, swedenborgite NaBe 4SbO7 and walstromite BaCa2Si3O 9

Research output: Contribution to journalArticlepeer-review

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.
