Abstract

The invention relates to a wavelength-converting reaction resin compound into which a wavelength-converting luminescent material and a thixotroping agent are mixed, wherein the luminescent material contains inorganic luminescent particles. The thixotroping agent is present, at least in part, in the form of nanoparticles. Methods of producing the reaction resin compound and light-emitting diode elements having such reaction resin compounds are indicated.
