Systematic Bathochromic Shift of Charge-transfer Bands of Mixed-metal Prussian-blue Nanoparticles Depending on Their Composition Ratios of Fe and Ni
Mixed-metal Prussian-blue nanoparticles, FexNiy[Fe(CN)(6)](2)center dot zH(2)O (x + y = 3, z = 8-12), were dispersed into n-butanol by hybrid surface modification with hexacyanoferrate(II) ions, [Fe-II(CN)(6)](4-), and n-hexylamines. In their transparent dispersion solutions, a systematic bathochromic shift of charge-transfer bands due to the Fe-II-CN-Fe-III components was observed depending on the metal composition ratios of Fe and Ni.
