Abstract

A lighting device is specified. The lighting device comprises a phosphor having the general molecular formula (MA) a (MB) b (MC) c (MD) d (TA) e (TB) f (TC) g (TD) h (TE) i (TF) j (XA) k (XB) l (XC) m (XD) n :E. In this case, MA is selected from a group of monovalent metals, MB is selected from a group of divalent metals, MC is selected from a group of trivalent metals, MD is selected from a group of tetravalent metals, TA is selected from a group of monovalent metals, TB is selected from a group of divalent metals, TC is selected from a group of trivalent metals, TD is selected from a group of tetravalent metals, TE is selected from a group of pentavalent elements, TF is selected from a group of hexavalent elements, XA is selected from a group of elements which comprises halogens, XB is selected from a group of elements which comprises O, S and combinations thereof, XC=N and XD=C and E=Eu, Ce, Yb and/or Mn. The following furthermore hold true: a+b+c+d=t; e+f+g+h+i+j=u; k+l+m+n=v; a+2b+3c+4d+e+2f+3g+4h+5i+6j−k−2l−3m−4n=w; 0.8≤t≤1; −3.5≤u≤4; 3.5≤v≤4; (−0.2)≤w≤0.2 and 0≤m<0.875 v and/or v≥l>0.125 v.

Claims (3)

1. A phosphor having the general molecular formula SrLi 3-2x** Al 1+2x** O 4-4x** N 4x** :Eu where 0.125≤x**≤0.875.

2. A phosphor having the general molecular formula SrLi 3-2x** Al 1+2x** O 4-4x** N 4x** :Eu where 0.125≤x**≤0.5.

3. A phosphor having the general molecular formula SrLi 3-2x** Al 1+2x** O 4-4x** N 4x** :Eu where 0.125≤x**≤0.45.
