Abstract
The local environments of Cd and Ph cations in Cd1-xPbxF2 as a function of x have been measured by means of extended X-ray absorption fine structure (EXAFS). The compositional dependence of disorder has been studied and reveals that the second shell structures for the Cd- and Pb-edges decrease with concentration for x < 0.6 and are completely washed out at x = 0.6. An increase in the second shell structure is observed as x increases from 0.6. However, the high values of the Debye-Waller factors on the Pb edges suggest a high degree of disorder around the Pb cations in the whole of Cd1-xPbxF2 mixed crystals.
