Abstract
In at least one embodiment, an optoelectronic semiconductor component includes an optoelectronic semiconductor chip. The semiconductor component includes a conversion element that is arranged to convert at least some radiation emitted by the semiconductor chip into radiation of a different wavelength. The conversion element comprises at least one luminescent substance and scattering particles and also at least one matrix material. The scattering particles are embedded in the matrix material. A difference in the refractive index between the matrix material and a material of the scattering particles at a temperature of 300 K is at the most 0.15. The difference in the refractive index between the matrix material and the material of the scattering particles at a temperature of 380 K is greater than at a temperature of 300 K.
