Abstract
The nature of the thermochromic effect is investigated in glasses containing AgCl microcrystals (MC). At temperatures above the melting point of microcrystals, the absorption spectrum consisting of two bands transforms into a single, very narrow, and intense band. This band is similar to absorption bands that appear in the spectra of silver-containing systems under the conditions ensuring metal coagulation. A model of the thermochromic process is proposed. According to this model, the narrow band is attributed to the spherical metal layer adsorbed on the wall of the cavity containing the AgCl melt. After the crystallization of AgCl, metallic islands in the form of oblate ellipsoids remain instead of the spherical layer. The role of secondary glass-formers is analyzed, and the evidence for the existence of a similar effect in glasses with CuCl is obtained.
