By electrodeposition in organic system,nio films with reversible electrochromic property were ***-doped tin oxide glass slices were used as substrates,*** voltammetry and ultraviolet-visible transmission spectroscopy were adopted to study the electrochromic properties of the *** resolution transmission electron microscopy(HRTEM) was employed to analyze the composition and structure of the *** is found that the films are composed of fine nio crystal grains of a few nanometers in diameter,endowing them with large visible light transmittance variation,rapid switch rate(*** response time) between the bleached and colored *** cycling durability reached 6000 cycles.
