Based on an analysis of absorption spectra from 4I9/2 ground state to the excited states of Nd3+ ions in Pb(MoO4)x(WO4)1–x crystals, the main spectroscopic characteristics, including the probabilities of intermultiplet transitions and radiative lifetimes, are determined with the help of Judd–Ofelt method. The values of Judd–Ofelt parameters Ω2 = 8.91 × 10–20 cm2, Ω4 = 4.50 × 10–20 cm2, and Ω6 = 3.89 × 10–20 cm2 are obtained for Nd3+ ions in Pb(MoO4)x(WO4)1–x crystals. The calculated radiative lifetime is compared with experimentally measured luminescence decay time.
