An optical converter for producing colored or white light from blue excitation light is provided. The converter has good scattering properties to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components. The optical converter includes material including one or more of a YAG ceramic, a LuAG ceramic, and a magnesium-aluminum ceramic exhibiting strong scattering.

Optical converter for high luminances

The invention in general relates to glass or glass-ceramic products. In order to protect the surface of such products against scratching, a silicon oxynitride coating with special composition is provided.

Glass or glass-ceramic substrate with scratch-resistant coating and method for the production thereof

The invention relates to an arrangement for fluorescence amplification including a substrate, a fluorescence amplifier coating applied to the substrate, and a thin fluorescencable material which lies on the coating and emits light with the emission wavelength &#x3bb;when it is exposed to excitation light of an excitation wavelength &#x3bb;. The fluorescence amplifier coating includes an interference layer system of high-index and low-index dielectric layers, which reflects at least the excitation light. What is crucial for the design of the coating is that the fluorescencable material applied to the coating is arranged on the surface of the coating in the region of the maximum of the electric field amplitude of the standing wave with the excitation wavelength &#x3bb;, which is formed during exposure to the excitation light.
