Abstract:
A method for producing a luminescent material includes producing a mixture of starting substances, wherein the starting substances have a first component and a second component. 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. The second component comprises oxygen and/or nitrogen. The method also includes annealing the mixture at a temperature of at least 1300° C. in a reducing atmosphere. After method the annealing, at least one or several phases are obtained. At least one phase comprises a luminescent material. The luminescent material 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 600 nm.
