A luminophore having the general empirical formula X′A′(AlA′)O:E′ that crystallizes in a tetragonal crystal system.

Yellow luminophore and light source

A phosphor may have the general formula EAADON:RE. EA may be selected from the group of divalent elements. A may be selected from the group of monovalent, divalent or trivalent elements. D may be selected from the group of trivalent or tetravalent elements. RE may be an activator element. 0&#x2264;x&#x2264;8, and &#x3b5;(4+4y+3z)=3(8&#x2212;x)+2x with the charge number y of element A, the charge number z of element D, and &#x3b5;=0.9-1.1.

Phosphor, method of producing a phosphor, and radiation emitting device

A luminophore may have the general empirical formula XAZO:E, where:

Luminescent substance and illuminating device

The invention relates to a red-emitting luminescent material of the formula AE16&#x2212;xCexSi17&#x2212;zAlzN32+y&#x2212;zO2&#x2212;y+z wherein AE=Mg, Ca, Sr and/or Ba, 0&#x3c;x&#x2264;2, 0&#x2264;y&#x3c;5, 0&#x2264;z&#x2264;3 and y+z&#x3c;2.

Phosphor, method for producing a phosphor and use of a phosphor

A phosphor from the class of nitridosilicates from the M-Al&#x2014;Si&#x2014;N system, comprising a cation M, wherein M is represented by Ca alone or is represented by a mixture of Ca with at least one further element from the group Ba, Sr, Mg, Zn, Cd, Li, Na, Cu, wherein the phosphor is activated with at least one element from the group Eu, Ce which partly replaces M, characterized in that the phosphor forms a phase that is to be assigned to the system M3N2-AlN-Si3N4, wherein the atomic ratio of the constituents M:Al&#x2267;0.375 and the atomic ratio Si/Al&#x2267;1.4.

Luminescent substance of the class of nitride silicates and light source having such a luminescent substance
