Figure 6
(a) Luminescence emission (300 K; 140 eV excitation) of a typical modern porcelain glaze; the sharp features arise from trace quantities of Dy3+. (b) OD-XAS (10 K) observed from this emission, when stimulating over the boron K edges. The post-edge features depend strongly on the B—O bond lengths and coordination. (c) OD-XAS (10 K) over a wider excitation range: the L edges of Si, K and Ca are observed, together with the K edges of B and O. The Dy N-edge assignation is only tentative.
