Hye Soo Lee, Ju Hyeon Kim, Joon-Seok Lee, Jae Young Sim, Jung Yoon Seo, You-Kwan Oh, Seung-Man Yang, and Shin-Hyun Kim, "Magnetoresponsive Discoidal Photonic Crystals towards Active Color Pigments," Advanced Materials, accepted for publication (2014).

Photonic microdisks were designed to have multilayered structure from photocurable suspensions by step-by-step photolithography. In each step of photolithography, either colloidal photonic crystal or magnetic particle-laden layer was stacked over windows of photomask. Sequential photolithography enables the creation of multilayered photonic microdisks of which brilliant structural colors are able to be switched by external magnetic field.
