a XRD and Rietveld refinements for PB-0, K-32 and Cs-5. b Crystal structures of PBNPs with varying degrees of N-coordinated Fe sites and alkali metal contents. c HRTEM images of PB-0, K-32 and Cs-5. The images below are enlargement of the areas within the square above. d 57Fe Mössbauer spectra of PB-0, K-32 and Cs-5. e Temperature-dependent magnetic susceptibility (χm-T) plots, the inset shows the effective magnetic moment (μeff) and unpaired electron number (n) of PB-0, K-32 and Cs-5. f Scheme of the structure regulation mechanism to PBNPs by different alkali cations (View from (200) direction).
