Ce-doped double borates Ba3 Gd(BO3 )3 and Sr3 Gd(BO3 )3 (Ce:BGB and Ce:SGB, respectively) were grown by the micro-pulling-down method, and the luminescence properties of the crystals were investigated and compared with those of Ce-doped H -Ba3 Y(BO3 )3 (Ce:H -BYB) crystals grown by the same method. Transmittance measurements showed the wavelength of absorption band was around 380H -BYB. The photoluminescence decay times of Ce:BGB, Ce:SGB, and Ce:BYB were 29.5H -BYB (∼400 photons/neutron).
► Ce-doped Ba3 Gd(BO3 )3 , Sr3 Gd(BO3 )3 , and H -Ba3 Y(BO3 )3 were grown by micro-pulling-down method. ► Ce3+ 5d–4f photoluminescence were observed. ► Light yield strength by 241Am were corresponding to 100, 270, and 400 photons/neutron.
