Abstract

The luminescence kinetics of the electron transition 5D0 → 7F2 (~613 nm) of Eu3+ ions has been studied in tungstates (Lu1 – xEux)2(WO4)3 and molybdates (Lu1 – xEux)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.
