Abstract

A radiation-emitting component includes a semiconductor chip and a conversion element. The semiconductor chip includes an active layer suitable for generating electromagnetic radiation and a radiation exit face. The conversion element includes a matrix material and a luminescent material. The conversion element is arranged downstream of the radiation exit face of the semiconductor chip. The matrix material comprises at least 40 wt. % tellurium oxide and is free of boron trioxide and/or germanium oxide. A method for producing such a radiation-emitting component is furthermore stated.
