Abstract (en)

[origin: WO2018069195A1] The invention relates to Mn4+-activated luminescence materials, to a method for the production thereof, and to the use thereof as luminescent materials or conversion luminescent materials in light sources. The invention further relates to an emissions-converting material containing the luminescent material according to the invention and to a light source that contains the luminescent material or the emissions-converting material according to the invention. The invention further relates to light sources, in particular LEDs, and lighting units, which contain a primary light source and the luminescence material or the emissions-converting material according to the invention. The Mn4+-activated luminescence materials according to the invention are particularly suitable for generating warm white light in LEDs.
