Y2-nAnMo4Sb2O18 (A = Pr, Sm, Eu, Tb, Dy, Ho, and Er; n = 0.02-2) solid solutions were synthesized by a solid-state method and studied for their lanthanide photoluminescence. They show concentration dependent lanthanide photoluminescence and existence of concentration quenching phenomenon. The emission intensity and the fluorescence-lifetime are found to be highest for an optimum concentration of a given lanthanide ion in the solid solution series studied. The neat photoluminescence of A2Mo4Sb2O18 (A = Pr, Sm, Eu, Tb, Dy, Ho, and Er) compounds involves partial concentration quenching. © 2015 Elsevier B.V. All rights reserved.

Nine new A2Mo4Sb2O18 (A=Ce, Pr, Eu, Tb, Ho, Er, Tm, Yb, Lu) compounds have been synthesized by solid-state reactions. They are isostructural with six reported analogues of yttrium and other lanthanides and the monoclinic unit cell parameters of all fifteen of them vary linearly with the size of A3 ion. Single crystal X-ray structures of eight A2Mo4Sb2O18 (A=Ce, Pr, Eu, Gd, Tb, Ho, Er, Tm) compounds have been determined. Neat A 2Mo4Sb2O18 (A=Pr, Sm, Eu, Tb, Dy, Ho, Er, Tm) compounds exhibit characteristic rare earth metal photoluminescence. © 2011 Elsevier Inc. All rights reserved.

Six new isostructural A2(Mo4Sb2O18) (A=Y, La, Nd, Sm, Gd and Dy) compounds have been synthesized by solid-state reactions and characterized by single crystal X-ray diffraction and spectroscopic techniques. They crystallize in C2/c space group with 4 formula units and contain A3+ cations and discrete centrosymmetric anionic (Mo4Sb2O18)6- aggregates, made of tetrahedral MoO4 and disphenoidal SbO4 moieties. They exhibit characteristic Sb3+ photoluminescence. © 2007 Elsevier Inc. All rights reserved.
