Abstract : We have measured the silver k-edge EXAFS for a number of photodoped arsenic sulphide films and determined the silver-sulphur coordination distance. This is very similar to the Ag25As25S50 glass, as is the near-edge region. Phase separation has been observed in some films by the appearance of a second shell in the Fourier transform.
