Abstract:
A conversion element, an optoelectronic component, an arrangement and a method for producing a conversion element are disclosed. In an embodiment an arrangement includes a conversion element including a wavelength converting conversion material, a matrix material in which the conversion material is embedded and a substrate on which the matrix material with the embedded conversion material is directly arranged, wherein the matrix material comprises at least one condensed sol-gel material selected from the group consisting of water glass, metal phosphate, aluminum phosphate, monoaluminum phosphate, modified monoaluminum phosphate, alkoxytetramethoxysilane, tetraethylorthosilicate, methyltrimethoxysilane, methyltriethoxysilane, titanium alkoxide, silica sol, metal alkoxide, metal oxane, and metal alkoxane, and a laser source configured to emit primary radiation during operation, wherein the conversion element is arranged in a beam path of the laser source, wherein the conversion element is mechanically immovably mounted with respect to the laser source, and wherein the primary radiation of the laser source is dynamically arranged to the conversion element.
