摘要

Optical limiting materials have been developed to protect optical sensors and photonic devices from laser-induced damage. In this study, the optical properties of five vegetable oils (olive, sesame, cherry, pumpkin, and grape seed) combined with molybdenum diselenide (MoSe2) nanosheets under continuous-wave laser radiation at 532 and 405 nm were investigated. Molybdenum diselenide nanosheets were added at different concentrations to evaluate improvements in the optical limiting threshold performance. At 532 nm, sesame and cherry seed oils showed no inherent optical limiting behavior, but with MoSe2 (0.5 g/L), both exhibited a threshold decrease to 76.24 mW. Pumpkin seed oil showed the greatest improvement, with its threshold reducing from 80.5 to 63.42 mW with MoSe2. At 405 nm, all oils exhibited native optical limiting responses, with grape, cherry, and pumpkin seed oils showing the lowest initial thresholds. MoSe₂ enhanced the performance, with pumpkin seed oil reaching 63.2 mW at 0.5 g/L concentration. These results confirm that MoSe2 nanosheets improve the nonlinear optical response of vegetable oils, indicating their potential as economical alternatives for optically limited applications.
