Реферат:	eng: Herein we report the growth of new RxLayScz(BO3)(4) (x + y + z = 4, R = Sm, Tb) crystals with large secondharmonic generation (SHG) responses. The obtained compounds, grown from eutectic LiBO2.LiF flux by the TSSG method, crystallize in the space group P321 with the cell parameters a = 9.800(15) angstrom and c = 7.9565(7) angstrom for Sm0.34La0.68Sc2.98(BO3)(4) and a = 9.7976(7) angstrom and c = 7.9567(12) angstrom f or Tb0.23Ta0.77Sc3(BO3)(4). These crystalline materials also exhibit luminescent properties related to the optical transitions of Tb3+ and Sm3+; specifically, Tb0.23La0.77Sc3(BO3)(4) shows a strong green emission that is dominated by the D-5(4) to F-7(5) transition. The studied crystals' SHG intensities were higher than those of KDP crystals, revealing their potential uses in various nonlinear optics applications.
