P. 333-338Abstract: Non-centrosymmetric borates K7CaY2(B5O10)3 have been synthesized by solid state reaction and the crystals were successfully grown by the top seeded solution growth method using K2O-B2O3-CaF2 flux. According to the single X-ray diffraction, the structure belongs to the R32 space group with lattice parameters a = 13.2516(2) Å and c = 14.9679(3) Å. IR, Raman, absorption spectra as well as data on melting temperature were obtained for the crystal. The short edge of UV absorption and SHG intensity comparable with KH2PO4 (KDP) suggests that this crystal is a promising nonlinear-optical material.
