Plasmonic Microspheres: Plasmonic Janus Microspheres Created from Pickering Emulsion Drops (Adv. Mater. 26/2020)

Jong Bin Kim Su Yeon Lee Nam Gi Min Seung Yeol Lee Shin‐Hyun Kim

In article 2001384, Shin‐Hyun Kim and co‐workers design plasmonic Janus microspheres using emulsion drops whose interface is decorated by particles. The emulsion drops made of acrylate resin are photopolymerized and the particles are removed. The directional deposition of the metal renders the top hemispheres as plasmonically colored and the position of the particles at the interface is precisely controlled by aging, which enables the tuning of the plasmonic property. The plasmonic colors can be switched on and off by controlling the orientation of the Janus microspheres with an external electric field.
