a Schematic of the conceivable dynamic scattering phenomenon by BoL-LC. Spheres in the structure represent the constituent elements (green: boron, red: oxygen, purple: potassium). b Diagram of a BoL-LC device fabricated using a comb electrode. c On/off optical switching induced by an applied voltage (1 V). Response speed of the device; d, e correspond to the changes of the on and off states, respectively. The error bars in d, e stand for the standard deviation of ten observed values. f Temperature dependency of the repetition feature in the BoL-LC device.
