• Thermal behavior, density, infrared absorption and X-ray photoelectron spectroscopy of Ag_xAs_<60-x>S_<40> bulk glasses (35 ≤ x ≤ 47.5) have been investigated to obtain structural information on glasses that exhibit photoinduced surface deposition (PSD) of Ag. The compositional trends in the range of 40 ≤ x ≤ 47.5, where the PSD effect is observed, were very different from those in the range of 35 ≤ x ≤ 40. The trends in the range of 40 ≤ x ≤ 47.5 can be explained by assuming the existence of excess Ag^+ ions in the glasses. The excess Ag^+ ions, which contribute to the PSD, may lie between isolated AsS_3 pyramids and bind loosely with surrounding S atoms.
