Abstract

The low temperature spectroscopic properties of Bi³⁺ impurities in the double perovskite, La₂MgTiO₆, is examined in this work. The luminescence is interpreted on the basis of localized Bi^{3+ 3}P_0,1 → ¹S₀ transition. Band structure calculations reveal that the bottom of the conduction band is composed of Ti⁴⁺ 3d orbitals. In La₂MgTiO₆, the Bi^{3+ 3}P_0,1 states fall below the Ti⁴⁺ 3d⁰ conduction band which permits the first observation of luminescence from the localized Bi^{3+ 3}P_0,1 excited state in a titanate host lattice.
