More Information
Summary:The invention relates to a method for producing a luminescent material, involving the following method steps: (A) producing a mixture of starting substances, wherein the starting substances have a first component and a second component, wherein the first component is selected from a group that comprises aluminum, silicon, at least one element of the 2nd main group of the periodic table and at least one element of the lanthanides and combinations thereof; wherein the second component comprises oxygen and/or nitrogen; (B) annealing the mixture at a temperature of at least 1300 DEG C in a reducing atmosphere, wherein, after method step (B), at least one or several phases are obtained, wherein at least one phase comprises a luminescent material (6), wherein the luminescent material (6) absorbs at least a portion of an electromagnetic primary radiation in the UV or blue range and emits an electromagnetic secondary radiation with an emission maximum of greater than or equal to 600nm.
