Polarization anisotropy of luminescent properties of europium (III) ions in low-symmetry C 2  sites is studied using monoclinic (sp. gr.  C 2/ c ) tungstate crystal KY(WO 4 ) 2 . The  5 D 0  →  7 F J  (where  J  = 0…6) transitions are characterized for the principal light polarizations. Polarization selection rules for the magnetic dipole  5 D 0  →  7 F 1  transition are presented. The stimulated-emission cross-sections for Eu 3+  ions relevant for laser operation are determined.
