Systematic Bathochromic Shift of Charge-transfer Bands of Mixed-metal Prussian-blue Nanoparticles Depending on Their Composition Ratios of Fe and Ni

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·zH2O (x + y = 3, z = 8–12), were dispersed into n-butanol by hybrid surface modification with hexacyanoferrate(II) ions, [FeII(CN)6]4−, and n-hexylamines. In their transparent dispersion solutions, a systematic bathochromic shift of charge-tr...

Zusammenfassung:Mixed-metal Prussian-blue nanoparticles, FexNiy[Fe(CN)6]2·zH2O (x + y = 3, z = 8–12), were dispersed into n-butanol by hybrid surface modification with hexacyanoferrate(II) ions, [FeII(CN)6]4−, and n-hexylamines. In their transparent dispersion solutions, a systematic bathochromic shift of charge-transfer bands due to the FeII–CN–FeIII components was observed depending on the metal composition ratios of Fe and Ni.
