Local changes in the short-range region of the PDF during the in situ solvothermal synthesis experiment (x = 0.24). (a) Low-r region of the raw PDFs. (b) Heating profile during the experiment, together with temporal evolution in peak position of (c) the first M—O and first M—M distances, (d) the third and sixth M—M distances, and (e) the refined coherent domain size, i.e. coherence length in the PDF. (f) The first M—M distance versus coherence length. The vertical dashed lines in (b)–(f) mark the end of an initial delay period before the first M—M distance expansion and the end of the gradual M—M expansion.
