Abstract: The invention relates to a method of manufacturing europium-doped (Ca1-xSrx)S (0£x£1) luminescent material with a short decay time and a high thermal extinction temperature, wherein the europium-doped strontium sulfide is subjected to at least a first caldnation step at high temperatures in the presence of at least one iodine compound. The invention further relates to the luminescent material as such and to its use for light-emitting components such as light-emitting diodes (LEDs) and laser diodes coated with luminescent materials.
