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. • Novell terbium-europium material has been synthesized. • The emission of the compound has been tuned to white from red. • The positions of 4f and 5d states have been determined. • Energy transfer processes and quenching mechanism have been appointed. • The influence of temperature on the energy transfer has been given.
