Abstract
The first steric-repulsion-based magnetically responsive photonic crystals (MRPCs) is constructed by synthesizing uniform superparamagnetic polyvinylpyrrolidone-coated Fe3 O4 colloidal nanocrystal clusters. The color tunable range of the MRPCs can not only cover almost the entire visible specztrum in solvents of diverse polarities, but also is insusceptible to ionic strength or pH values, facilitating the practical applications of MRPCs.
