Abstract: Disclosed is a conversion element (100). The conversion element (100) comprises: a conversion coating (16), which contains a wavelength-converting conversion material; a first encapsulation coating (30) on a first main surface (20) of the conversion coating, said first encapsulation coating having a thickness of between 10 μm and 500 μm; and a second encapsulation coating (32) on a second main surface (22) of the conversion coating, said second encapsulation coating having a thickness of between 0.1 μm and 20 μm. Also disclosed are an optoelectronic semiconductor component (200) and a method for producing conversion elements.

Abstract: A method for producing a plurality of conversion elements (10) is specified, comprising providing a carrier substrate (1), introducing a converter material (3) into a matrix material (2), applying the matrix material (2) with the converter material (3) to individual regions (8) of the carrier substrate (1) in a non-continuous pattern, applying a barrier substrate (5) to the matrix material (2) and to the carrier substrate (1), and singulating the carrier substrate (1) with the matrix material (2) and the barrier substrate (5) into a plurality of conversion elements (10) along singulation lines (V), wherein the conversion elements (10) in each case comprise at least one of the regions (8) of the matrix material (2).
