Abstract: A red-emitting phosphor composed of an M-Al-Si-N system, comprising a cation M, wherein M is represented by at least one of the elements Ca or Ba or Sr and, if appropriate, can additionally be combined with at least one further element from the group Mg, Zn, Cd, wherein the phosphor is activated with Eu, which partly replaces M, and wherein the phosphor additionally contains LiF.

Abstract: A thermally stable phosphor made of the M-Si—O—N system, having a cation M and an activator D, M being represented by Ba or Sr alone or as a mixture and optionally also being combined with at least one other element from the group Ca, Mg, Zn, Cu. The phosphor is activated with Eu or Ce or Tb alone or as a mixture, optionally in codoping with Mn or Yb. The activator D partially replaces the cation M. The phosphor is produced from the charge stoichiometry MO—SiO2—SiN4/3 with an increased oxygen content relative to the known phosphor MSi2O2N2:D, where MO is an oxidic compound.

Abstract: Oxidonitridoaluminosilicate compounds (I) are new. Oxidonitridoaluminosilicate compounds of formula (M x-tAl aSi bN 11-2xO 4x:Z t) (I), are new. M : Ba or Sr; Z : Eu (preferred), Mn or Ce; and x : less than 0 or greater than or equal to 2; and a, b : not defined. Where the ratio of a and b, related to aluminum or silicon, is 3:5-3:9. Independent claims are included for: (1) a radiation-emitting device, comprising a radiation source, which emits a primary radiation, and (I) as phosphor, which is arranged in the optical path of the radiation source, where the primary radiation is completely or partly converted into a longer-wave secondary radiation; and (2) the preparation of (I).
