Abstract

The new compound K2Eu(MoO4)(PO4) has been synthesized. The compound is isostructural to the known potassium lanthanide molybdate phosphates (Ln = Nd, Sm, Dy, Yb, Lu). It crystallizes in space group Ibca (no. 73) with the unit cell parameters a = 19.734 Å b = 12.301 Å c = 6.978 Å V = 1693.8 Å, R p = 2.19%, R wp = 2.97%. K2Eu(MoO4)(PO4) decomposes above 1000°C and has a rather high luminescence intensity. The 5D0-7F2,4 electric dipole transitions are noticeably stronger than the 5D0-7F1,3 magnetic dipole transitions because of the noncentrosymmetric coordination environment of the europium ions in the complex molybdate phosphate.
