摘要：

EXAFS, PAS and ESR measurements have been carried out on the Se-S mixed chains isolated in the channels of mordenite crystal. In the isolated Se1-xS(x) mixed chains the Se-Se and S-S like-pairs are somewhat preferable to the Se-S unlike-pairs. The photo-induced absorption bands appear in the mixed chains at low temperatures, which are accompanied by ESR signal. The induced ESR signal contains a strongly anisotropic component with average g-value higher than 2. The anisotropic component can be assigned to the neutral dangling-bond defect C1(0).
