The luminescence properties of Yb²⁺ in some oxidic host lattices have been investigated. In some host lattices the Yb²⁺ luminescence is quenched (aluminates, silicates, oxides) while in other host lattices Yb²⁺ luminescence is observed (halides, borates, sulphates, phosphates). A prediction of whether or not Yb²⁺ will show luminescence can be made by considering the luminescence properties of Eu²⁺ in the same host lattice. The lower quenching temperatures of Yb²⁺ luminescence are explained by the lower stability of Yb in the divalent state in comparison with Eu²⁺ in these host lattices.
