Luminescent Properties of Nd3+ Ions in Pb(MoO4)x(WO4)1–x Crystals

Abstract

The spectral and luminescent investigations of the Pb(MoO₄)_x(WO₄)_1–x crystals doped by the Nd³⁺ ions have been carried out. The investigations have made possible to determine the energies of the Stark levels of the ⁴F_3/2 metastable state, ⁴I_9/2 ground state, ⁴I_11/2 and ⁴I_13/2 excited states, as well as the cross section of transitions associated with the intense lines of emission bands in ⁴F_3/2→⁴I_11/2 and ⁴F_3/2→⁴I_13/2 channels. The emission bands in this crystal are relatively wide, so one would expect the creation of a tunable laser and a broadband amplifier in the 1060 and 1330 nm wavelength regions.
