Abstract

The luminescence kinetics of the electron transition ⁵D₀ → ⁷F₂ (~613 nm) of Eu³⁺ ions has been studied in tungstates (Lu_{1 –} _xEu_x)₂(WO₄)₃ and molybdates (Lu_{1 –} _xEu_x)₂(MoO₄)₃. Luminescence decay times are very close in both compounds at x ≥ 0.2, while a significant difference is observed at x < 0.1. Observed behavior is attributed to the difference in electronic structure of compounds.
