AWAXS results: the pair-correlation function g(r) of the undoped a-Sr(PO3)2 (upper plot) is compared with the differential pair-correlation functions Δg(r)Sr (middle plot) measured at the Sr K edge. Δg(r)Eu (lower plot) is obtained on the doped sample at the Eu K edge. The first peak of g(r), at about 1.6 Å, represents the P—O shell of the phosphate matrix, while the second peak represents the O—O and Sr—O shell contributions. The first peaks of Δg(r)Sr and Δg(r)Eu represent the Sr—O and Eu—O coordination shells, respectively.
