摘要：

We have investigated the ternary glass AgI-Ag2S-AgPO3, where the ratio of AgI:Ag2S is 1:1. As the amount of the dopant salts increases, the glass transition temperature decreases, and the conductivity increases to about 5.7 x 10(-3) (Omegacm)(-1) at room temperature for an 88% mol fraction of AgI+Ag2S. The structure factor, S(Q), shows a prepeak at low Q values (0.64.9 Angstrom(-1)), as observed in AgI-AgPO3 glasses, but not in pure AgPO3 or in Ag2S-AgPO3. The concentration dependence of the prepeak indicates medium range atomic correlations growing in concentration and size. (C) 2002 Elsevier Science B.V. All rights reserved.
