| Outline of Final Research Achievements |
We have successfully prepared water-dispersion solutions of Prussian blue (PB) and its Ni-replaced analog (Ni-PBA) nanoparticles. Double layer (DL) films composed of PB (bottom layer) and Ni-PBA (top layer) NPs have been simply fabricated on indium-tin-oxide (ITO) glass substrates by spin-coating using their water-dispersion solutions, and electron-rectification phenomena of the DL films have been investigated. Via reconstitution of d-π bonding networks among NPs by low-temperature sintering at 120-150°C, the spin-coated films well adhered on the ITO substrates and fragility of the films was surprisingly improved. The bottom layer of the PB NPs behaves as a high-performance electron-blocking layer against the top layer of the Ni-PBA NPs. The electron-rectification phenomena occurred cation-selectively of potassium ions.
