Summary: In this work, Cu3VSe4 nanocrystals were used to enhance laser protection performance. The nanocrystals exhibited higher saturation intensity and broader nonlinear spectral response than the C60 benchmark. A flexible optical limiter goggle prototype based on the nanocrystals significantly attenuated the incident laser beam. The excellent nonlinearity of Cu3VSe4 nanocrystals was attributed to quasi-static dielectric resonance behavior and a large two-photon absorption cross-section.
