“…The traditional methods for the synthesis of Fe 3 O 4 nanoparticles include the coprecipitation method [15][16][17], microemulsion method [18][19][20], and sol-gel method [21][22][23], etc. However, the Fe 3 O 4 nanoparticles prepared by these three methods are usually uncontrollable, and the monodispersity cannot meet the requirements for the assembly of MRPCs; however, the solvothermal method is commonly used for the synthesis of monodisperse Nanomaterials 2024, 14, 852 2 of 17 nano Fe 3 O 4 to construct MRPCs due to its flexibility and adjustability.…”

In this paper, we designed and investigated a reduction-based method to synthesize controllably monodisperse superparamagnetic nano Fe3O4 colloidal clusters for magnetically responsive photonic crystals. It was shown that the addition of ascorbic acid (VC) to the system could synthesize monodisperse superparamagnetic nano Fe3O4 and avoided the generation of γ-Fe2O3 impurities, while the particle size and saturation magnetization intensity of nano Fe3O4 gradually decreased with the increase of VC dosage. Nano Fe3O4 could be rapidly assembled into photonic crystal dot matrix structures under a magnetic field, demonstrating tunability to various diffraction wavelengths. The nano Fe3O4 modified by polyvinylpyrrolidone (PVP) and silicon coated could be stably dispersed in a variety of organic solvents and thus diffracted different wavelengths under a magnetic field. This is expected to be applied in various scenarios in the field of optical color development.
