Zusammenfassung: | ZrN–SiO 2 core–shell particles were prepared, where the ZrN core nanoparticles and SiO 2 shell were designed to exhibit localized surface plasmon resonances (LSPRs) and structural coloring. The heating of ZrO 2 nanoparticles with Mg 3 N 2 under a nitrogen gas flow produced ZrN nanoparticles with a diameter in the range of 10–20 nm. The dispersion of ZrN nanoparticles in water exhibited an absorption maximum at approximately 700 nm owing to LSPRs. An SiO 2 shell was formed on the ZrN nanoparticles using a sol–gel process. Scanning transmission electron microscopy confirmed the formation of ZrN–SiO 2 core–shell particles containing ZrN particles with a diameter of approximately 10 nm. The SiO 2 shell thickness was controlled by varying the reaction time to form SiO 2 . The use of particles as a structural component of a structural color material owing to the high uniformity of the size of obtained core–shell particles was investigated. The obtained ZrN–SiO 2 core–shell particles were arrayed on a glass substrate using a layer‐by‐layer method. The particle‐stacked film of the ZrN–SiO 2 core–shell particles exhibited the maximum reflection depending on the particle size of the SiO 2 shell. |
