Abstract
An optoelectronic unit includes a semiconductor chip configured to emit primary radiation with a first wavelength range during operation of the optoelectronic unit. The optoelectronic unit also includes a component including an optically active material. The component is arranged at least partially in the beam path of the semiconductor chip. The optically active material is not intended to be excited by the primary radiation with the first wavelength range. The optically active material incudes a proportion in the component of 0.004 wt %, inclusive, to 1 wt %, inclusive.
