 Serium-doped lutetium-mitrium oxy-orthosilicate, CE-LYSO, is a well-known single crystal scintillator used in medical imaging and security scanners. Recent development of high-power UV lead, matching its absorption band, questions the possibility to use CE-LYSO in a new way, as lead pumped solid-state light source. Since CE-LYSO is available in large-size crystals, we investigate its potential as a luminescent concentrator. This paper reports an extensive study of the performance in close relation to the spectroscopic properties of this crystal. It gives the reasons why the CE-LYSO crystal tested in this study is less efficient than CE-YAG for luminescent concentration, limited quantum efficiency, and high losses coming from self-absorption and from excited-state absorption are playing key roles. However, we demonstrate that a CE-LYSO luminescent concentrator is an innovative source for solid-state lighting, pumped by a peak power of 3400W in quasi-continuous wave regime, 40 microseconds, 10 Hz.
