    Abstract Fluorite is one of the most common minerals in the crust and is of widespread economic importance. It shows strong UV-excited luminescence, variously attributed to defects within the fluorite structure and lanthanide ...
  • Structural state of rare earth elements in eudialyte-group minerals 
    Borst, Anouk M; Finch, Adrian A.; Friis, Henrik; Horsburgh, Nicola J.; Gamaletsos, Platon N.; Goettlicher, Joerg; Steininger, Ralph; Geraki, Kalotina (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
