Abstract
An optoelectronic component includes a semiconductor chip which during operation emits electromagnetic primary radiation of a first wavelength range, and at least one conversion element. The conversion element is designed to emit electromagnetic secondary radiation of a second wavelength range. The electromagnetic secondary radiation is in the infrared spectral range. The conversion element includes at least one wavelength-converting material and a matrix material. The wavelength-converting material is a rylene dye.
