Abstract:
A method for producing a converter element, a converter element and a light emitting device are disclosed. In an embodiment a method for producing a converter element providing at least one phosphor and a liquid polysiloxane resin and preparing a cured polysiloxane powder from a first fraction of the liquid polysiloxane resin. The method further includes preparing a mixture including the at least one phosphor, the cured polysiloxane powder and a second fraction of the liquid polysiloxane resin, casting and curing the mixture to a cured layer and singulating the cured layer.
