The optical and electrical properties of the metal photo-doped chalcogenide glasses were studied. The optical absorption of the chalcogenide glasses <I>e.g.</I>, the As–S, As–S–Te, and As–S–Se systems) was increased by the photo-doping of such metals as Ag and Cu in the region of their absorption edges. The electrical conductivity of the glasses also increased with the photo-doping of the metals. The effective band gap obtained from the results of the temperature dependency of the electrical conductivity decreased with the increase in the amount of metal which was photo-doped in the glasses. The results obtained in this study suggest that the metals photo-doped in the chalcogenide glasses behaved as structural modifiers of the glasses, and that the state of density in the gap was increased by the metal photo-doping.
