Undoped and -doped lithium aluminate singe crystals have been grown using micro-pulling down ( -PD) technique. After cutting and polishing, optical properties and scintillation characteristics of the crystals were examined. From the transmittance measurements, -doped crystal showed absorption band around 270 nm, which is corresponding to the transition between and states. Ultra violet emission peak appeared around 360 nm under 270 nm excitation. The emission decay time was calculated to be about 17.3 . 5.5 MeV alpha-ray excited radioluminescence spectra exhibited intense luminescence band at 360 nm due to the transitions. By the pulse height spectra neutron source excitation, the scintillation light output of -doped was found to be about 8700 ph/n.
