Abstract

An optoelectronic component includes a semiconductor chip that is able to emit radiation having a wavelength of 400 nm to 490 nm, a conversion element including a reactive polysiloxane matrix material, a wavelength converting phosphor and filler nanoparticles, wherein the filler nanoparticles have a diameter of smaller than 15 nm and modify the refractive index and yield a mixture when added to the reactive polysiloxane matrix material.
