Ce3+-doped borate crystal fibers of Li6Gd(BO3)3 (LGBO) and Li6Y(BO3)3 (LYBO) compositions are grown by the micro-pulling down (μ-PD) method for potential application in developing new neutron detectors. The ternary equilibrium diagram of Li2O–Gd2O3–B2O3 is drawn and the preparations of homogeneous mixed LGBO and LYBO powders and growth conditions for single crystal fibers are discussed. Absorption, excitation and X-ray luminescence spectra are investigated. Absolute light yield derived from energy spectra and kinetic decay curves measured under α- and γ-scintillations of Ce3+-doped LGBO and LYBO single crystal fibers is provided.
► Ternary equilibrium diagram of Li2O–Gd2O3–B2O3 system has been drawn. ► Un-doped and Ce doped Li6Gd(BO3)3 and Li6Y(BO3)3 single crystal fibers has been grown by micro-pulling down. ► Photopeak has been observed and fibers can be used as neutrons detectors in n-γ-fields.
