摘要：

Reflection, emission, and excitation spectra of CaS:Pb2+ and CaSe:Pb2+ are measured at 300, 80, and 6K. At higher concentrations of Pb2+ ions, the emission and exeitation bands due to the Pb2+ dimer are observed besides those of the Pb2+ monomer. Theoretical calculation of energy levels of the dimer of Tl+‐type ions is made on the basis of the localized electron model. The values of the spectroscopic parameters appearing in the energy matrices are determined so that the electronic levels obtained experimentally and theoretically may coincide with each other.
