Seung Yeol Lee, Jongkook Choi, Jong-Ryul Jeong, Jung H. Shin, and Shin-Hyun Kim, "Magnetoresponsive Photonic Microspheres with Structural Color Gradient", Advanced Materials, accepted for publication (2016).

Photonic Janus particles are created by alternately sputtering silica and titania on microspheres to have a structural color gradient. In addition, the microspheres are rendered magnetoresponsive. The Janus microspheres with optical and magnetic anisotropy enable on-demand control over orientation and structural color through manipulation of an external magnetic field, thereby being useful as active color pigments for reflection-mode display.
