Research Abstract

Basic features of A3R(BO3)3(A=Ba; R=Y, Sm-Yb) double borates were investigated with high-temperature X-ray structural analysis; R=Sm-Tb show H phase, R=Tm-Yb show L phase, and R=Dy,Ho,Y show H phase in high temperature and L phase in low temperature. Three cation sites (3a,3b, and 18f) in Sr3Y(BO3)3 were investigated by X-ray structural analysis with anomalous scattering, and the sites 3a was confirmed to be occupied by Y, 3b by Sr, and 18f by Sr/Y, suggesting the rare-earth doped element occupies 18f. Single crystal of Ce doped A3R(BO3)3 was grown by FZ method and the scintillation signal of the crystal excited by alpha-particles were clearly observed, suggesting the application as scintillator crystals.
