We prepared two samples with in-plane asymmetry: the first sample is the square lattice comprising asymmetric-shaped TiO₂ nanoparticles. The second sample is non-Bravais lattice of Si nanoparticles array, supporting quasi-BIC states at normal incidence. Using these asymmetric nanoantennas, we investigated non-centric directional photoluminescence and sensitivity to the surrounding refractive index.
