Abstract: The invention relates to an optoelectronic component, which, in at least one embodiment, comprises an optoelectronic semiconductor chip having an emission side and a conversion element on the emission side. The conversion element is configured for conversion of a primary beam emitted by the semiconductor chip in operation as intended. The conversion element is divided into at least one first layer and one second layer. The first layer is arranged between the second layer and the emission side. The first layer comprises a first matrix material having fluorescent particles introduced therein. The second layer comprises a second matrix material having fluorescent particles introduced therein. The first matrix material of the first layer has a higher index of refraction than the second matrix material of the second layer.

Abstract: An optoelectronic component and a method for producing an optoelectronic component are disclosed. In an embodiment, an optoelectronic component includes a semiconductor chip configured to emit radiation and moisture-stable glass particles arranged in a beam path of the semiconductor chip, wherein the moisture-stable glass particles are filler, scattering particles and/or filter particles, wherein each of the moisture-stable glass particles comprises a moisture-sensitive core of a glass material, and wherein the core is covered with at least one moisture-stable inorganic coating.
