Abstract
The pseudobinary alloy exists as a single phase at all compositions. With change in composition the optical absorption edge at 300 K changes continuously from 0.4 eV for PbS to 4.6 eV for SrS. For compositions with , -type and -type thin films have been prepared by doping with Tl or Ag and with Bi, respectively. Similar single-phase behavior and composition dependence of the energy gap are found with .
