Abstract (en)
[origin: DE102007020782A1] The radiation emitting device (1) comprises a radiation-emitting functional layer (2) emitting a primary radiation (4) in the blue region, a radiation conversion material arranged in a beam path of the functional layer, and a radiation conversion luminescent material (31) converting a part of the primary radiation into a secondary radiation (5). The wavelength of the primary radiation is 400-470 nm. The material of the functional layer has a semiconductor. The luminescent material is activated in the blue-region and/or the UV-region and in the range of 360-470 nm. The radiation emitting device (1) comprises a radiation-emitting functional layer (2) emitting a primary radiation (4) in the blue region, a radiation conversion material arranged in a beam path of the functional layer, and a radiation conversion luminescent material (31) converting a part of the primary radiation into a secondary radiation (5). The wavelength of the primary radiation is 400-470 nm. The material of the functional layer has a semiconductor. The luminescent material is activated in the blue-region and/or the UV-region and in the range of 360-470 nm, and has a maximum emission of 512+- 3 nm. The conversion material is formed as layer-like radiation conversion body and the functional layer covers on one or more sides. The body partially converts the primary radiation into secondary radiation and the non-converted primary radiation superimposes itself with the secondary radiation, so that a mixture is existed from the primary- and secondary radiation. The conversion material comprises additional luminescent material. The body has a transparent matrix, in which the radiation conversion luminescent material is present. The luminescent material is represented by Ca 2. 6 2 5Eu 0. 0 5 5Mg 0. 3 2SiO 4Cl 2 in the range of 0-0.5. An independent claim is included for a procedure for the production of a radiation emitting device.
