摘要：

Changes induced by Pb2+ impurities in the optical behaviour of crystals of the perovskitelike KMgF3 have been studied. Absorption and emission spectra of samples, containing dopant concentrations ranging from 0.1 to 10 mole%, show that isolated Pb2+ ions, replacing substitutionally Mg2+ ions in the cubic lattice of KMgF3, assume a configuration very similar to that of (ns)2 univalent metal impurities in crystals of alkali halides. Aggregates of Pb2+ ions in KMgF3 are also found, even at low doping levels. © 1990.
