3C-SiC is expected to be a next-generation material for TiO₂ because of its high refractive index and low extinction coefficient over a wide wavelength range, including the near UV region. In this study, we established a fabrication method for 3C-SiC nanoantenna stickers and evaluated the optical properties of the fabricated samples, demonstrating that the emission intensity of YAG:Ce³⁺ is larger than that of conventional TiO₂ nanoantenna stickers. The diffraction conditions of surface lattice resonance (SLR) were controlled by tensile tensioning of the sample, and the emission directivity of YAG:Ce³⁺ was successfully modulated.
