摘要：
Na2S forms with Ga2S3 stable glasses having a large region of composition. The glasses are studied by Raman and infrared spectroscopies. According to the relative proportion of gallium atoms in the glass the observed frequencies are assigned to internal vibrations of tetrahedral GaS4 groups and sulphur bridge stretching or corner-shared or edge-shared tetrahedra. The observed changes in the properties of chalcogenide glasses in the Ga2S3-Na2S system support the proposed structural model.
