Crystal structure and luminescence properties of europium-doped iodo- and telluromolybdate compounds

Abstract : Synthesis of large crystals of the europium-doped iodo- and telluromolybdate compounds is described and structural determination is performed. K(NH4)[RE(IMo6O24)(H2O)(5)]. 4H(2)O, REIMo, RE = La-Eu, is triclinic and (NH4)(3)[RE(TeMo6O24)(H2O)(5)]. 4H(2)O, RETeMo, RE = La-Eu, monoclinic. The rare-earth ion occupies in both compounds C-s symmetry site. The luminescence analysis with europium as a local structural probe confirms the crystallographic structure. The emission spectra are similar in all compounds.
