Edge absorption spectra of crystalline and glassy lead thiogermanate (PbGeS3) have been measured in the temperature range from 77 to 470 K. It is shown that the dependence of the absorption coefficient on the photon energy for the glassy and crystall

The crystal structure PbGeS3 and SnGeS3 compounds consists of infinite chains of top-sharing [GeS4] tetrahedra. These chains are ‘laced’ together by chains of ψ-octahedra coordinating the lead (tin) atoms. The vibrational spectra of ordered and
