内容記述 |
Nickel–cobalt (Ni–Co) oxide thin films were directly grown on the fluorine-doped tin oxide (FTO)-coated glass substrates via a simple one-pot solution process using various ratios of Ni and Co precursors. All the Ni–Co oxide samples were composed of nanosheet structures that were vertically aligned on the surface of the substrates. The nanosheets of the Ni10–Co0, Ni8–Co2, Ni6–Co4, and Ni4–Co6 oxide samples uniformly covered the surface, whereas those of the Ni2–Co8 and Ni0–Co10 oxide samples were sparsely distributed. As the ratio of Co to Ni was increased, the width of the nanosheets gradually increased. Cyclic voltammetry (CV) at a scan rate of 50 mV/s showed that the Ni8–Co2 and Ni6–Co4 oxide samples exhibited better electrochemical performance than the other oxide samples. Furthermore, all Ni–Co oxide samples except Ni0–Co10 exhibited a reversibly sustainable in situ transmittance change with cycling (1000 cycles, 30,000 s) and a relatively fast switching time of less than 4 s for the colored and bleached states. Herein, the color modulation from transparent to black nanosheet-structured Ni–Co oxide samples was effectively tuned by adjusting the ratios of the Ni and Co precursors. |
