X-ray diffraction analysis of double molibdates CsDy(MoO4)2 and CsDy0.93Eu0.07(MoO4)2: 1. Crystal structure

It is shown that crystals CsDy(MoO4)2 and CsDy0.93Eu0.07(MoO4)2 at room temperature can be assigned to a monoclinic system. The observed changes in the powder diffraction pattern with decreasing temperature are associated with structural phase transitions; the strutural changes are not identical both in the Eu3+ doped and undoped samples.
