Abstract

A radiation-emitting optoelectronic component may include a semiconductor chip or a semiconductor laser which, in operation of the component, emits a primary radiation in the UV region or in the blue region of the electromagnetic spectrum. The optoelectronic component may further include a conversion element comprising a first phosphor configured to convert the primary radiation at least partly to a first secondary radiation having a peak wavelength in the green region of the electromagnetic spectrum between 475 nm and 500 nm inclusive. The first phosphor may be or include BaSi4Al3N9, SrSiAl2O3N2, BaSi2N2O2, ALi3XO4, M*(1−x*−y*−z*) Z*z*[A*a*B*b*C*c*D*d*E*e*N4-n*On*], and combinations thereof.
