    Abstract: A phosphor is specified. The phosphor has 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, -E=Eu, Ce, Yb and/or Mn, XC=N and XD=C. 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 0.125 v.

    Abstract: Phospher particles with a Protective Layer and a method for producing phosphor particles with a protective layer are disclosed. In an embodiment the method includes treating Si-containing and/or Al-containing phosphor with an acid solution, wherein a pH value of the acid solution is maintained within a range of pH 3.5 to pH 7 for a period of at least 1 h, wherein an Si-containing layer is formed on the phosphor particles, wherein the Si-containing layer has a higher content of Si on a surface than the phosphor particles, and/or wherein an Al-containing layer is formed on the phosphor particles, wherein the Al-containing layer has a modified content of aluminum on the surface than the phosphor particles and tempering the treated phosphor particles at a temperature of at least 100° C. thereby producing the protective layer.
