摘要：

The structure and EU(2+) luminescence of the compound Sr2LiSiO4F are described. Crystal data: FW = 293.26, P2(1)/m (No. 11), monoclinic, a = 6.5825(9), b = 5.4158(8), c = 6.9266(6) Angstrom,beta = 112.525(8)degrees, V = 228.09(5) Angstrom(3),Z = 2, R = 0.049, R(W) = 0.058 for 760 averaged reflections. The structure contains two crystallographically distinct Sr atoms; both are 10 coordinate and bound by eight O atoms and two F atoms. The Li atom occupies a distorted square pyramid, and the Si atom a slightly distorted tetrahedron. When doped with the lanthanide ion EU(2+), the compound exhibits a bright green emission with a maximum intensity at 531 nm.
