Abstract
Luminescent concentrators allow to design new light sources combining high power and high brightness. So far, they have been developed from Ce:YAG [1] or Ce:LuAG [2] crystals with yellow emission and blue LED pumping. It is possible to extend the luminescent concentrator concept to other wavelengths, with the right combination of pump LED/ luminescent material. Cerium-doped lutetium-yttrium oxyorthosilicate (Ce:LYSO) is a well-known single crystal scintillator used in medical imaging and security scanners. Recent developments of high power UV LED, matching its absorption band, questions the possibility to use Ce:LYSO in a new way: as LED-pumped solid-state light source. Since Ce:LYSO is available in large size crystals, we investigate its potential as a luminescent concentrator.
