Kuz'micheva, V. Rybakov, E. Zharikov, D. Lis, K. Subbotin] The structure of single crystals grown by the Czochralski technique from (Na0.500La0.495 − x CexEr0.005)MoO4 (x = 0.10, 0.125, 0.15, 0.175, 0.20) melts in a weakly oxidizing atmosphere (99-99.5% N2 + 0.5-1% O2) (NLM-0) was studied by x-ray diffraction. Some of the crystals received short-term annealing at 1000°C (NLM-2) and/or long-term annealing at 700°C (NLM-1). The oxygen in the structure of NLM:Er,Ce-0 and NLM:Er,Ce-1 with x = 0.20 was found to occupy two crystallographic sites at random. In the structure of the NLM:Er,Ce-2 crystal with x = 0.20, the oxygen atoms are fully ordered into one site, as in the scheelite structure. It cannot be ruled out that these crystals contain both Ce3+ and Ce4+ ions. Pleiades Publishing, Inc., 2006 Kuz'micheva G. Lomonosov State Academy of Fine Chemical Technology, pr.
