A phosphor is disclosed. In an embodiment a phosphor includes an inorganic substance which includes, in its composition, at least an element D, an element Al, an element AX, an element SX and an element NX where D includes one, two or more elements selected from the group consisting of Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, alkali metals and Yb, Al includes one, two or more elements selected from the group consisting of divalent metals not included in D, SX includes one, two or more elements selected from the group consisting of tetravalent metals, AX includes one, two or more elements selected from the group consisting of trivalent metals, and NX includes one, two or more elements selected from the group consisting of O, N, S, C, Cl, and F, wherein the inorganic substance has the same crystal structure as Sr(SraCa1-a)Si2Al2N61.
