Abstract

An optoelectronic component includes an optoelectronic semiconductor chip that, during intended operation, generates primary radiation coupled out of the semiconductor chip via an emission side of the semiconductor chip; and a first conversion element on the emission side, wherein the first conversion element includes a first matrix material and first phosphor particles in the form of quantum dots, the first phosphor particles are distributed and embedded in the first matrix material, and the first matrix material is formed by a polysiloxane in which an atomic percentage of carbon is smaller than an atomic percentage of oxygen.
