摘要：

The physical properties of Pb2+ impurities in the perovskite-like lattice of KMgF3 are very similar to those of (ns)2 ions in alkali halides. The impurity inhomogeneous distribution leads to high dopant levels in the bottom region of the crystals, with a segregation coefficient equal to 0.020. The optical features of the 336 nm emission support its attribution to luminescence of Pb2+ ions from the relaxed excited B state. © 1991, Taylor & Francis Group, LLC. All rights reserved.
