Nature News reports that British and Canadian chemists have developed synthetic opals that can very quickly switch between various colors when a few volts of electricity are applied to them.
This “is an opal-based technology that provides electrically tunable color of any wavelength.
This research project is being led by Geoffrey Ozin, a chemist at the University of Toronto, Canada, and his group, and by Ian Manners of the University of Bristol, UK, and his own group. The project also involved André Arsenault of Opalux, a Toronto-based start-up company which was spun off from the University of Toronto, and by Daniel Puzzo, of the Department of Chemistry at the University of Toronto.
