摘要：

A new perovskite crystal, BaLiF3 doped with lead was subjected to e- irradiation. A metal related color center involving the Pb2+ ion emitting at 880 nm was identified. The excitation spectrum at 70K shows that there are three bands peaking at 744, 487 and 305 nm (also present in the absorption spectrum) that are responsible for this emission. These bands, either in relative transition magnitudes and energy positions, are the expected ones for the lead perturbed color center, Pb+(1), the isoelectronic specie of the laser active Tl0(1) center.
