摘要:
The invention relates to a luminescence conversion led based illumination deice that emits primarily radiation in the range of from 370 and 430 nm of the optical spectrum (peak wavelength). Said radiation is converted to radiation having a longer wavelength using three luminescent substances that emit in the red, green and blue range.

摘要:
An illumination device with at least one LED as the light source, the LED emitting primary radiation in the range from 370 to 430 nm of the optical spectral region (peak wavelength), this radiation being partially or completely converted into radiation of a longer wavelength by three phosphors which are exposed to the primary radiation from the LED and which emit in the blue, green and red spectral regions, so that white light is formed. The conversion is achieved at least with the aid of a phosphor which emits blue light with a wavelength maximum at 440 to 485 nm, and with the aid of a phosphor which emits green light with a wavelength maximum at 505 to 550 nm, and with the aid of a phosphor which emits red light with a wavelength maximum at 560 to 670 nm.

摘要:
A method for producing high-density, translucent, scintillator ceramics by way of a pressure-less sintering carried out at an elevated temperature. According to the method, particles of a MOS composition are prepared using a specific wet milling method whereby being reduced, in particular, to a particle size of less than 10 μm. The particles are compacted to form compacted bodies with green densities of up to 50% and higher. The sintering may be carried out under specific sintering parameters.

摘要:
A moldable and curing reflector material for an X-ray detector is disclosed. It includes a detector material which converts X-rays into light and is divided into a plurality of segments separated by the reflector material. The reflector material includes a polymer matrix which contains a first optically reflecting material and also a finely distributed gas and/or a second optically reflecting material, which is different than the first optically reflecting material. An X-ray detector is further disclosed, which contains a material of this type, along with a process for producing a material of this type and a process for producing an X-ray detector.
