Реферат:	eng: The EuBO3-ScBO3 system was investigated by solid state synthesis and DSC methods. In this system, a new EuSc(BO3)(2) compound was found. It crystallizes in the R3 space group with unit cell parameters of a = 4.8939(1) angstrom and c = 16.2663(5) angstrom. Whereas another compound in the system EuSc3(BO3)(4) possesses two modifications: a low-temperature alpha-C2/c (a = 7.687(1) angstrom, b = 9.810(2) angstrom, c = 12.021(2) angstrom, and beta = 105.379(4)degrees) and a high-temperature beta-R32 (a = 9.7473(1) angstrom and c = 7.9205(2) angstrom). The alpha-EuSc3(BO3)(4) crystal was grown with LiBO2-LiF flux, and beta-EuSc3(BO3)(4) was obtained by the solid state synthesis. All of the obtained crystals exhibited typical Eu3+ luminescence spectra with peaks at 589 nm, 596 nm, 615 nm, 657 nm and 689 nm, which corresponded to the D-5(0) -> F-7(J) (J = 0, 1, 2 and 4) electron transitions. The strongest peak of luminescence was located at 615 nm and corresponded to the D-5(0) -> F-7(0) transition.
