| Abstract: | A new yttrium borate compound K3Y3(BO3)4 has been obtained in the K2O-Y2O3-B2O3 ternary system. Its structure, determined from single crystal X-ray diffraction data, shows that it belongs to space group P21/c with unit cell dimensions of a = 10.4667(16) Å, b = 17.361(3) Å, c = 13.781(2) Å and β = 110.548(8)°. The structure consists sheets of [Y8B8O24]∞ linked by out of sheet BO3 groups and Y ions to form a three-dimensional framework. The luminescent properties of Eu3+ and Tb3+ doped K3Y3(BO3)4 materials have also been studied. |
