N2 - The invention relates to a luminescent substance made of metal nitrido-silicate that is actived using divalent manganese. Said luminescent substance can be described by general formula MxSiyN2/3x+4/3y:Mn2+ (wherein 0 <x and 0 <y), wherein M represents one or more metal ions, Si represents silicon which can be partially substituted by germanium, aluminum, boron, gallium, scandium, and/or phosphorus, and N represents nitrogen which can be partially substituted by oxygen. The invention further relates to a white-emitting LED comprising an element that emits exciting radiation and at least the disclosed luminescent substance which absorbs some of the exciting radiation and emits in a different spectral region.
