Abstract The new compounds Ln[M(OH)6Mo6O18]·11H2O (Ln = Tb, Eu and M = Al, Cr) were synthesized and their luminescence properties analysed and discussed. Results show that there is a very efficient energy transfer from Eu3+ (Tb3+) to Cr3+ ions in Eu[Cr(OH)6Mo6O18]·11H2O and Tb[Cr(OH)6Mo6O18]·11H2O. The transfer strongly quenches Eu3+ (Tb3+) luminescence and(More)
This study concerns the formation of complexes with actinides at oxidation state +IV, from Th to Am, through a lacunary heteropolyanion ligand P(2)W(17)O(61)(10-). The preparation of original single crystals of complexes with 1:2 stoichiometry provided structural data through single-crystal X-ray diffraction for the entire An(IV) series. An(IV) atoms in(More)
Following the previous work, luminescent properties of Eu3+ ions in powder sample Eu[Cr0.1, Al0.9 (OH)6 Mo6 O18 ].11H2O was studied in detail. Experimental results revealed that there were three Eu3+ centers in the system. The dominant one can transfer its excitation energy to Cr3+ ions, as studied before. By conducting site-selective excitation at low(More)
