METHOD FOR PRODUCING A CERAMIC CONVERSION ELEMENT, CERAMIC CONVERSION ELEMENT AND OPTOELECTRONIC DEVICE

摘要

A method for producing a ceramic conversion element comprising the following steps is provided: - providing a ceramic basic body in the green state, said ceramic basic body comprises a phosphor, which converts light of a first wavelength range into light of a second wavelength range, - structuring the ceramic basic body in the green state such that pixel regions are formed within the ceramic basic body, said pixel regions being separated from each other by grooves, while the ceramic basic body comprises a continuously connecting part, which connects the pixel regions along a main surface, wherein - the structuring is performed by one of the following methods: laser structuring, micro-embossing, sawing, grinding, etching in combination with a mask, sand blasting, jet cutting. Alternatively, a ceramic basic body in the sintered state is provided and structured accordingly. Further, a conversion element as well as a optoelectronic device is described.
