Abstract

In single crystals of AgCl, BaCl₂, PbCl₂, SrCl₂, KPb₂Cl₅ with an unextended phonon spectrum (E less than 200 cm^-1), doped by Dy, the luminescence spectrum was found to cover a wide range from visible region to IR (4.3 mkm for KPb₂Cl₅), including well pronounced 1.31 mkm band, which is important for using in telecommunication amplifiers. The Rare Earth impurity was shown to enter the host matrice as RE³⁺ in chlorides, the only type of impurity centers being formed in the case of rhombic MeCl₂ crystals with Me equals Ba, P, S.
