N2 - The undoped and 0.5% Ce3+-doped strontium metaborate SrB 2O4 single crystals has been grown successfully by micro-pulling down method with radio frequency (RF) heating system, and scintillation characteristics including optical properties and radiation response were studied for these crystals. The Ce3+-doped SrB 2O4 crystal showed absorption band around 240-320 nm, which is corresponding to the 4f-5d transition of Ce3+. Intense emission band at 375 nm due to the Ce3+ 5d-4f transition was observed under 241Am 5.5 MeV α-ray excitation. The scintillation decay time showed fast (50 ns) and slow (1430 ns) components ascribed to the Ce 3+ 5d-4f transition and lattice defect in the crystal, respectively. The scintillation light yield of Ce3+-doped SrB2O 4 was calculated to be about 1000 ph/n under 252Cf irradiation.
