Eu2+ 0.1, 0.5, 1, and 2mol% doped LiCaAlF6 single crystalline scintillators were grown by the micro-pulling down (μ-PD) method. Eu2+ 2mol% doped LiCaAlF6 was also prepared using the Czochralski method. In the transmittance spectra, 4f–5d absorption lines appeared around 200–220 and 290–350nm. An intense emission at 375nm due to Eu2+ 5d–4f transition was observed under 241Am α-ray excitation. When 252Cf excited pulse height spectra were measured, Eu 2% doped one showed the highest light yield of 29,000ph/n with 1.15μs decay time. Using the 2inchφ Czochralski grown one coupled with the position sensitive photomultiplier tube covered by Cd mask with various size (1, 2, 3, and 5mm) pin holes, thermal neutron imaging was examined. As a result, the spatial resolution turned out to be better than 1mm.
