Single crystals of Eu-doped calcium orthoborate have been grown by micro-pulling (μ-PD) technique with radio frequency heating system, and its transmittance, photoluminescence and radiation responses were investigated. In transmittance spectra, Eu-doped crystal showed broad absorption band around 200-450 nm, which is due to the complex of charge transfer (CT) transition and 4f-4f transition of Eu3+. Intense Eu2+ 5f-4f and Eu 3+ 4f-4f emission peaks were observed when excited to 265 nm and 385 nm, and the calculated decay times were 230 ns and 1.5 ms, respectively. 241Am 5.5 MeV α-ray excited radioluminescence spectra indicated both Eu2+ 5f-4f and Eu3+ 4f-4f emission peaks.
