The property of certain dyes of changing color when placed in an electric field.
- ‘This charge-shift couples with an electric field within a cell membrane, resulting in electrochromism.’
- ‘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.’
- ‘Eight signals at 522 nm were averaged in recordings of the electrochromism and 32 in measurements with pH indicators.’
- ‘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.’
