| Crystals | Light yield (photon/neutron) | Decay time (ns) | Emission wavelength (nm) | Transparency (t=10mm) |
|---|---|---|---|---|
| Ce:LiCAF | ～5,000 | 40 | 280～320 | ＞90％ |
| Eu:LiCAF | ～40,000 | 1,600 | 360～390 | ＞90％ |
LiCAF single crystals are excellent materials for neutron/gamma discrimination because of their low gamma-ray sensitivity due to their low density of 2.99 g/cm3 . The Eu-doped LiCAF has a large luminescence and the Ce doped LiCAF has a short decay time.
We commercialize crystals, arrays, and fibers for BNCT. The raw Li is available in natural and 6Li 95% enriched, and the neutron sensitivity can be adjusted. LiCAF flexible sheet is a transparent sheet with 0.9 to 3.6x1021 atom/cm3 fine LiCAF crystals dispersed in silicone resin.
It can be used as an alternative to 3He, neutron imaging, neutron diffraction, and survey meter.
