Abstract
The optical gap and the glass transition temperature show monotonic and nonmonotonic changes with x in (Ge0.3S0.7)100-x –(Sb0.4S0.6) x and (Ge0.42S0.58)100-x (Sb0.4S0.6) x glasses respectively. The relationship between the optical gap and the glass transition temperature obeys the formula obtained by DeNeufville and Rockstad. The electrical conductivity is not greatly changed in either series of glasses, and the addition of Sb2S3 brings about no appreciable change in the ESR shape for Ge30S70, a higher g-shift for Ge42S58 and a decrease in the spin density for both glasses. These results can be explained by noting that the structure around Ge in Ge42S58 becomes S-richer by the incorporation of Sb2S3, whereas the structure of Ge30S70 tends to form solid solutions of GeS2 and Sb2S3 with excess S-S bonds.Keywords
