Abstract

A radiation-emitting optoelectronic device is provided. The radiation-emitting optoelectronic device includes a semiconductor chip that, when the device is in operation, emits primary radiation of a wavelength of between 600 nm and 1000 nm. A conversion element includes a conversion material comprising ions of one or more metals selected from a group comprising La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Cr, Pb and Mg. The conversion material converts the primary radiation emitted by the semiconductor chip virtually completely into secondary radiation of a wavelength of between 1000 nm and 6000 nm.
