N2 - The EuBO3-ScBO3system was investigated by solid state synthesis and DSC methods. In this system, a new EuSc(BO3)2compound was found. It crystallizes in theR3̄ space group with unit cell parameters ofa= 4.8939(1) Å andc= 16.2663(5) Å. Whereas another compound in the system EuSc3(BO3)4possesses two modifications: a low-temperature α-C2/c(a= 7.687(1) Å,b= 9.810(2) Å,c= 12.021(2) Å, andβ= 105.379(4)°) and a high-temperature β-R32 (a= 9.7473(1) Å andc= 7.9205(2) Å). The α-EuSc3(BO3)4crystal was grown with LiBO2-LiF flux, and β-EuSc3(BO3)4was 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 the5D0→7FJ(J= 0, 1, 2 and 4) electron transitions. The strongest peak of luminescence was located at 615 nm and corresponded to the5D0→7F0transition.
