An optoelectronic component and a method for producing an optoelectronic component are disclosed. In an embodiment an optoelectronic component includes a semiconductor chip including a plurality of pixels, each pixel configured to emit electromagnetic primary radiation from a radiation exit surface and conversion layers located on at least a part of the radiation exit surfaces, wherein the conversion layers comprise a crosslinked matrix having a three-dimensional siloxane-based network and at least one phosphor embedded in the matrix, and wherein the conversion layers have a thickness of ≤30 μm.

Steel sheet coating compositions in which polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an anhydrous, encapsulated, aluminum particle paste, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and optionally a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit surface formation of iron oxides and to improve steel sheet surface characteristics.

The present disclosure relates to coated non-metallic substrates and coated metallic substrates, and methods for producing such coated substrates. A variant of the method is characterized in that a mat or glossy coating is underneath a metallic layer obtained in some cases by way of vapor deposition and/or sputtering. In another variant, the metallic is sufficiently thin so that it remains transparent or translucent to visible light. The coated substrates may include multiple layers such as metallic layers, polysiloxane layers, a color layer, a conversion layer, a primer layer, and/or a transparent or colored layer. An application system for applying a metallic layer to at least one surface of a substrate may include a plasma generator and/or a corona system for treating one or more layers by plasma treatment and/or corona treatment.
