Title: Lanthanide oxide sulphide oxide sulphide selenide red phosphors - with interstitial metal ion activator and halide coactivator useful in colour TV tube
Inventor: WICHELHAUS WINFRIED DIPL CHEM
IPC: C09K11/88
Filed: 1979-01-18
Abstract: Phosphors are based on lanthanide (oxide) sulphide (selenide) (I) of the formula Ln10(S1-xSex)15-yOy (in which Ln is La, Ce, Pr, Nd, Sm, Eu, Gd, Ib, Dy, Ho, Er, Tm, Yb, Lu, Y, Sc and/or Pm. x and y are 0-1). They contain metal ions (II) as activators, which occupy interstices in the crystal, and halide ions (III) as co-activators, in amts. sufficient to produce luminescence. Phosphors are specified for use as red components in colour TV tubes. In contrast to ZnS, the luminescence of these phosphors is not suppressed by "killer" ions, e.g. Fe ions, and, in principle, all metals except alkali(ne earth) metals can be used as (II). The phosphors are useful for replacing Y2O2S:Eu, which gives an undesirable line spectrum and has emission maxima in too short a region (617 and 627nm).
