原文摘要如下：This paper demonstrates eccentric one-dimensional (1-D) core-shell photonic crystal balls (PCBs) with self-displaying structural colours and responsiveness to both the direction and strength of external magnetic field (H), as well as their controllable and versatile light intensity-guiding morphology-controllable polymerization method. In this protocol, the irradiation of a unidirectional UV light upon photopolymerizable magnetically responsive photonic crystal (MRPC) droplet templates in a vessel with reflected bottom substrate enables the light intensity within the droplets to decrease from the outer to inside in a noncentrosymmetrical manner, generating PCBs with an MRPC liquid core eccentrically encapsulated in a 1-D PC hydrogel shell under H by controlling the light irradiation time. Besides the magnetic rotation, the resultant PCBs are capable of collectively self-displaying structural colour without input energy due to the inner-eccentric 1-D PC hydrogel shells. Furthermore, they can display dynamically tunable bi-photonic band-gaps by H benefiting from the coexistence of the PC hydrogel shell and MRPC liquid core. When dispersed in viscous media suppressing the magnetic rotation, they may also exhibit orthogonal bi-photonic band-gaps, enabling a wide-angle display character of 1-D photonic crystals with different colour patterns. These unique modulations in optical properties promise important applications of the as-developed PCBs in bionic chromatic materials, energy-saving display, switchable signage and anti-counterfeiting coating.
