The title compound, K(5)EuLi(2)F(10), belongs to so-called self-activated materials containing lanthanoid ions within the matrix. A common feature of these systems is a large separation between the closest lanthanoid ions, which is one of the crucial factors governing the self-quenching of luminescence. The crystal structure of K(5)EuLi(2)F(10) is isotypic with other K(5)RELi(2)F(10) compounds (RE = Nd, Pr). As expected from the lanthanoid contraction, the unit-cell volume for crystal with Eu(3+ ...[more]
