Figure 8. Phase mapping in the Bi-Cu-V oxide system. (A) Photographs of 4 sputter-deposited composition libraries in Bi–Cu–V oxide system; (B) Representative XRD patterns collected on the composition libraries, where each XRD pattern is plotted at the location of the composition in the Bi–Cu–V composition graph; (C) The DRNets solution for one composition, showing that the XRD pattern of the Bi_0.11Cu_0.39V_0.50 oxide sample is composed of 42% BiVO₄ and 58% Cu₂V₂O₇; (D) The resulting phase map of the primary 14 of the 21 phases identified by DRNets, where each phase has a unique symbol whose point size indicates phase concentration in the composition graph^[133].
