“…Gunjakar et al [268] deposited nanocrystalline NiO thin films and studied structural, optical and LPG sensing properties. The maximum response of 36.5% was recorded on exposure to 0.3 vol% of LPG at 698 K. Highly porous nickel oxide thin films [269,270] were prepared on ITO glass with a following heat-treatment process. The NiO thin film annealed at 573 K exhibited electrochromism and good memory effect.…”

“…It is well-known that the peak potential separation between the oxidation peak and the reduction peak is used as a measure of reversibility [18] . The peak potential separation in Fig.4(a) is obviously smaller than the corresponded separation in Fig.4(b) which indicates that the PANI film on NF substrate has better reaction reversibility.…”

The polyaniline (PANI) films doped with complex acid (sulfuric acid and sulfosalicylic acid) were prepared using the potentiostatic method on bare nickel flake (NF) and flexible polyethylene terephthalate (PET)/indium tin oxide (ITO) substrates. The contents of the PANI films ， surface elements, electrochromic property and electrical conductivity were characterized by energy dispersive X-ray spectrometer (EDS), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The experimental results show that differences exist among cycle stability, redox reversibility and response time of polyaniline films on these two kinds of substrates, but the electrochromic phenomenon of the PANI films is in substantial agreement. The equilibrium transmittance spectra in the visible region (400-800 nm) for the PANI film on flexible PET/ITO substrate was obtained at different applied potential from -0.4 to 1.5 V. The results show that the transmittance of the PANI film by applying voltage is adjustable in a row and has excellent electrochromic performance.

“…Based on our experiment, the optimum condition was found to be with the heat treatment temperature at 500°C. To evaluate the performance of the NiO film, material, electrical, and optical measurements were applied to characterize the film [12]. Compared with recent studies [13][14][15][16], the electrodeposited NiO electrochromatic film exhibited broad wavelength range modulation between 300 nm and 700 nm, fast modulation speed, and high coloration efficiency in this study.…”

In this study, we propose two-step method of electrochemical deposition and heat treatment to fabricate electrochromic NiO films. A precursor NiO film was electro-deposited on fluorine-doped tin oxide (FTO). Then, the deposited film was crystallized with heat treatment. X-ray diffraction (XRD) was used to examine the crystalline structure and scanning electron microscope (SEM) was used to analyze the surface morphologyfor the film in different deposition and heat treatment conditions. Moreover, the cyclic voltammetry (CV) and optical performance of the film was evaluated. Based on multiple material and optical analysis, the film grown with plating solution with a pH value of 8.0 treated by heat treatment at 500ºC was the most desirable electro chromatic film. The fabricated NiO electrochromic film shows promise for use in future device applications.
