Spectral transmission and images of the device at different voltages. a The spectral transmission was recorded from 380 to 780 nm, and images of the device in (b): the bleached state at 0 V and c coloured state at –1.5 V. The circular switchable area has a diameter of 11 mm. Source data are provided as a Source Data file
