The following new compounds are reported: Mg5TiB2O10(ludwigite structure), Mg5SnB2O10(orthopinakiolite structure) and Mg3ZrB2O8(warwickite structure). The luminescences of the systems Mg5(Sn,Tl)B2O10and Mg3(Zr,Ti)B2O8were 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.
