Abstract

The absorption spectra of Cu⁺ and Ag⁺ in alkali halide crystals have been studied for some time by way of ordinary absorption and emission spectroscopy.¹ It has been established that the near ultraviolet transitions are due to 3d¹⁰→3d⁹4s for Cu⁺ and 4d¹⁰→4d⁹5s for Ag⁺, and that these occur at considerably higher energies (1-2 eV) in the crystal than in the free ion. A detailed understanding of the band shapes and their assignment to specified transitions had not been achieved, however.
