%X K<sub>5</sub>GdLi<sub>2</sub>F<sub>10</sub> compound doped with Tb<sup>3+</sup> and Eu<sup>3+</sup> was synthetized. The excited states of these lanthanide ions were analyzed up to VUV range at 125,000 cm<sup>−1</sup> (80 nm). Strong coupling between terbium and europium was found. The energy transfer processes from terbium to europium mainly depend on fast migration. The lifetime of <sup>5</sup>D<sub>4</sub> multiplet in the presence of europium is shorter by about 30
