The luminescence of doped and undoped BaLn2(MoO4)4 (Ln = La,Gd)

Abstract

The luminescence of nominally pure BaLn2(MoO4)4 (Ln = La,Gd) is reported. Below 300 K molybdate emission is observed. The following activators were investigated: Eu3+, Tb3+, Pb2+ and Bi3+. The two lanthanide ions show their characteristic emission, the two s2 configuration ions give an emission in which the host-lattice group as well as the activator is involved. The luminescence properties of these compositions are discussed and compared with those of related materials.
