The light-radiating semiconductor component has a radiation-emitting semiconductor body and a luminescence conversion element. The semiconductor body emits radiation in the ultraviolet, blue and/or green spectral region and the luminescence conversion element converts a portion of the radiation into radiation of a longer wavelength. This makes it possible to produce light-emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body. A particularly preferred luminescence conversion dye is YAG:Ce.

Light-radiating semiconductor component with a luminescence conversion element

The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed. The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a powder of Ce-doped phosphors and the luminous substance pigments have particle sizes &#x2266;20 &#x3bc;m and a mean grain diameter d&#x2266;5 &#x3bc;m.

The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a phosphorous group of the general formula A.sub.3 B.sub.5 X.sub.12 :M, and the luminous substance pigments have particle sizes&lt;20 .mu.m and a mean grain diameter d.sub.50 &lt;5 .mu.m.

Wavelength-converting casting composition and its use

An optoelectronic device, e.g. for integrated circuits, has an Si, II-VI or III/V semiconductor layer and an LaF.sub.3 or La.sub.1-x X.sub.x F.sub.3 insulating layer which is doped with Nd or Er to generate an optical signal whose wavelength is determined by the 4f ions used. The insulating layer can be grown epitaxially on the semiconductor layer and the lanthanide element ion substituting for a metal ion of the material forming the insulating layer has the same valence as the metal for which it is substituted.
