a Powder XRD patterns for the sol-gel synthesised series between 10–80 degrees. b Is an expansion of the data shown in a, highlighting the low angle (002) and (003) diffraction peaks, which correspond to the P2 and O3 structures respectively. c Plot of P2 content against radial potential, including a linear fit where r2 = 0.99.
