Progress on Rapidly and Self-Assembly Magnetically Responsive Photonic Crystals With High Tunability and Stability

Abstract

Magnetically induced self-assembling is considered a novel method to form photonic crystals (PCs) by the directive arrangement of nanoparticles (NPs) under a magnetic field. Magnetically responsive PCs (MRPCs) have become one of the most promising materials due to their adjustable bandgap along with the field intensity and direction, and rapid and reversible response. In this paper, we review the basic principles of MRPCs, the research progress of magnetically induced self-assembling PCs including synthesis and modification of magnetically induced NPs, the formation of an ordered structure of MRPCs, the non-spherical materials self-assemble into PC structure, and the non-magnetic materials self-assembling into PC structure. And then we also summarize the regulatory factors of the physical and chemical responses under magnetic field, and give an outlook as to the applications of MRPCs.
