We report the synthesis and self-assembly of Si@SiOxNy core-shell particles, scattering infrared light. They were produced by decomposing a Si coordination complex alongside cyclohexasilane, under supercriticalconditions. Core and shell dimensions were controlled through precursor stoichiometry and relative concentration. The electric and magnetic multipoles were characterized using a custom-built static light scattering spectrometer. Simulations show that the magnetic and electric responses are respectively located in the core and shell. The particles were self-assembled into metasurfaces and optically characterized usingellipsometry.< Réduire
