Popis: | A library of relative absorptivities of the C-N stretching modes for a series of Prussian blue analogues (PBAs), AxMy[M′(CN)6]z·nH2O (A = alkali cation; M, M′ = transition metals), has been assembled based on analysis of Fourier transform infrared (FTIR) spectra. Chemical variables including transition metal identity, cation identity, stoichiometry, and oxidation state have been considered. The absorptivities for individual PBAs were then applied to determine the composition of core–shell particles with varying shell thickness and the results correlate well with analyses derived from energy dispersive X-ray spectroscopy (EDS). Knowledge of relative absorptivities allows generally accessible FTIR methods to contribute to quantitative characterization of multiple phase Prussian blue analogue samples and PBA heterostructures. |
