| Popis: | 93 The electrochromic materials are capable of changing their optical properties (transmittance and/or reflectance) under applied electric potentials; when that potential is stopped or it goes on reverse, these materials keep or return to its original optical state in a reversible way. The variation of the optical properties is caused by of insertion/extraction of cations in the electrochromic film. The as-deposited LPD-NiO film is also uniform and transparent. The LPD-NiO film is light gray after coloring; the transparency ratio (ΔT%) can reach about 48% at the wavelength of 550 nm. After annealing in 300oC, the bleached state almost approaches that of original state before colored. We expect that the electrochromic device combined LPD-TiO2 and LPD-NiO films can enhance the coloration efficiency. |
