Abstract: Methods for producing wavelength converters are described. The methods include sintering a mixture consisting essentially of first particles and second particles to form a sintered article. In embodiments the first particles consist essentially of particles of β-SiAlON or precursors thereof, and the second particles consist essentially one or more sintering aids or precursors thereof. In embodiments the sintered article has a density that is greater than or equal to about 90% of a theoretical bulk density of the mixture, and is configured to convert primary light incident thereon to secondary light, wherein the secondary light exhibits a peak with a full width half maximum of greater than 0 to about 60 nanometers (nm) within a wavelength range of about 495 nm to about 600 nm.

Abstract: A method and device for slurrying a suspension, the device including a mixing container with an inlet opening configured to introduce the suspension into the mixing container, a distributor element having a collecting container and an outlet arm fastened to the collecting container, and a shaft with a longitudinal axis, with the shaft and the distributor element arranged inside the mixing container, and the distributor element rotatable around the shaft. The collecting container has a collecting opening that permits passage of the suspension from the inlet opening into the distributor element, the outlet arm has an outflow opening that lets the suspension leave the distributor element, and the outlet arm permitting the suspension to flow out of the distributor element, with a flow of the suspension causing a torque on the distributor element so that the torque supports a rotation around the shaft.

Abstract: A light-emitting component includes a light-emitting element and a housing with a cavity. The housing includes a housing material that absorbs at least 80 percent of light in the visible range. The cavity is formed by a limiting wall, formed by a housing surface, and a plane of the element. The light-emitting element arranged within the cavity of the housing and positioned above the element plane includes an emission side located opposite to the element plane. The cavity is at least partially filled with a transparent material composed of a first material and a second material, wherein the first material at least partially covers the limiting wall, and the second material at least partially covers the emission side. A boundary surface is formed between the first material and the second material. A first refractive index of the first material is smaller than a second refractive index of the second material.
