The growth of Y2O3, Sc2O3, and Lu2O3 single crystals using the micro-pulling-down method is reported. Crystallinity, optical transmittance, and scintillation characteristics including emission spectra, pulse height spectra, and decay kinetics under α-ray excitation of the grown crystals were studied. The light yields of Y2O3, Sc2O3, and Lu2O3 crystals were estimated from the pulse height spectra excited by 241Am 5.5 MeV α-rays, in about 920±92 ph/5.5 MeVα, 370±37 ph/5.5 MeVα, and 150±15 ph/5.5 MeVα, respectively. The scintillation decay times of Y2O 3, Sc2O3, and Lu2O3 crystals were estimated with following fast/slow parameters 30.1/184, 14.6/51.3, and 16.7 ns, respectively. Furthermore, α-ray imaging was performed using Y2O3 crystal.
