      abstract     = {K$_5$GdLi$_2$F$_{10}$ compound doped with Tb$^{3+}$ and
                      Eu$^{3+}$ was synthetized. The excited states of these
                      lanthanide ions were analyzed up to VUV range at 125,000
                      cm$^{−1}$ (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 $^5$D$_4$ multiplet in the presence of europium
                      is shorter by about 30\% in comparison to singly doped
                      terbium compounds. The character of the decay curve of the
                      $^5$D$_4$ multiplet is mono-exponential. Non-exponential
                      character was discovered in the case of $^5$D$_1$ europium
                      multiplet in the presence of terbium. The nature of this
                      quenching was determined to be dipole-dipole interaction
                      with critical distance 9.96 Å. The energy transfer is
                      temperature dependent.},
