Spinning of a cogwheel-like particle and self-assembled hexagonal platelets. a, b Polarizing optical micrographs obtained with red imaging light and under linearly polarized blue light illumination Pe perpendicular to n0 a, and at 45 to n0 b, when platelet rotates. c Corresponding angular speed versus time for Pe at 45° to n0. d Polarizing optical micrograph obtained with red imaging light and under linearly polarized blue light with Pe at −45° to n0. e Corresponding angular speed and azimuthal orientation angle φ versus time. Scale bars are 5 µm
