Abstract

Phospho-tungstate glass doped by Eu(III) was selectively excited into its vitreous or crystalline components. The ⁵D_o → ⁷F₁ emission consists of three distinct, relatively narrow lines indicating total removal of ⁷F₁ degeneracy. Based on group-theoretical analysis, the holohedrized site symmetry of Eu(III) is most likely C_2h (compatible with the conventional point-groups C₂ or C_s) or C_i. The exceptional blue-shift of ⁵D_o in glasses is at the same time rationalized by some EuO distances being unusually short.
