摘要：

Novel rare-earth borate KBaTB2O6 was synthesized using a conventional solid-state reaction method. The crystal structure of KBaTB2O6 has been determined by the Rietveld analysis, which demonstrates that the final chemical composition is K0.46Ba0.54Tb0.49BO3 and KBaTB2O6 is isomorphous with KBaY(BO3)(2) and crystallizes in the planar trigonal [BO3](3-) group R-3 m with lattice parameters of a=5.4562(4) angstrom, c= 17.8629(2) angstrom, and Z=3. Tunable emission in red wavelength range was realized by doping and controlling Eu3- ions content into KBaTB2O6. The critical energy transfer distance calculated by the concentration quenching theory was 6.64 angstrom and the energy transfer from Tb3+ to Eu3- tools place via a resonance-type mechanism.
