A method for producing an optoelectronic component is described with the steps of providing monomeric structural units, providing nanoparticles in a liquid medium, mixing the monomeric structural units and the nanoparticles in the liquid medium so that a starting sol is formed, introducing an acid into the starting sol to adjust a pH value, at least partial condensation of the monomeric structural units to form a network, wherein the nanoparticles are at least partially covalently bonded to the network, so that a sol-gel material is formed, applying the sol-gel material to a semiconductor chip, curing the sol-gel material to form a coating material. Furthermore, an optoelectronic component is specified.
