| abstract | The following new compounds are reported: Mg5TiB2O10 (ludwigite structure), Mg5SnB2O10 (orthopinakiolite structure) and Mg3ZrB2O8 (warwickite structure). The luminescences of the systems Mg5(Sn,Tl)B2O10 and Mg3(Zr,Ti)B2O8 were measured. The results are discussed in terms of delocalization in clusters of titanate octahedra. A general scheme for the luminescence of Ti4+-activated compositions is given. The composition Mg5SnB2O10: Ti is a very efficient luminescent material for titanium concentrations below some 20 mole percent. |
