Abstract:
A new luminescent material based on complex borate NaBaY(BO3)2 doped with Tb3+ and Eu3+ ions was obtained by high-temperature solid-state synthesis. Using X-ray diffraction analysis it was shown that NaBaY(BO3)2:0.07Tb3+:0.1Eu3+ crystallizes in trigonal system with the space group R-3m and isotypic with the mineral buetschliit K2Ca(CO3)2. The crystal structure of the phosphor is layered, formed from [BO3] triangles, [YO6] octahedra, [BaO9] and [NaO9] polyhedra. The calculated unit cell parameters for NaBaY(BO3)2:0.07Tb3+:0.1Eu3+ are: a=5.3510(6) Å, c=17.9338(3) Å, V=444.71(2) Å3. The luminescent properties of NaBaY(BO3)2:0.07Tb3+:0.1Eu3+ were studied.
