释义	electrochromism /ɪˌlɛktrə(ʊ)ˈkrəʊmɪz(ə)m / noun [mass noun] Chemistry The property of certain dyes of changing colour when placed in an electric field.This charge-shift couples with an electric field within a cell membrane, resulting in electrochromism.... These membrane-bound ASP probes were shown to exhibit electrochromism resulting from a charge - shift mechanism in which energies of absorption, excitation, and emission are modulated by the membrane electric field strength. Relative changes in the emission spectral amplitude resulting from excitation spectral shifts or effects other than electrochromism on dye response are not addressed in this study. Derivatives electrochromic adjective ... An electrolyte layer conducts ions back and forth between the electrochromic layer and an ion storage layer. It's done with ‘layers of different electrochromic polymers’ and the system includes a color-matching camera and pre-visualization screen.
