“…As can be seen, the binding energies of the elements were observed at 715.6, 546.3, 531.6, 367.0, 355.5, 353.0, 284.0, 181.9, 162.0 and 69.15 eV, respectively. According to the literature, [34][35][36][37][38][39][40] they were identified as the characteristic peaks of Fe 2p, Au 4p 3 , O 1s, N 1s, Au 4d 3 , Au 4d 5 , C 1s, Zr 3d, Au 4f and Br 3d, respect-ively. The characteristic peaks of Zr 3d indicated that the phosphate sites produced by PLC were successfully combined with Zr 4+ .…”
