Antimonene, a novel two-dimension (2D) Group-VA material, shows excellent electrical and optical properties. In this work,antimonene nanosheets or nanoparticles were obtained by laser irradiating antimony powder in isopropanol solution anddiff erent morphology of antimonene were obtained by adjusting diff erent laser irradiation parameters, including irradiationtime and irradiation energy. The nonlinear absorption properties of antimonene with diff erent morphologies under 532 nmnanosecond laser were studied by Z-scan technology. It was found that the reverse-saturation absorption ability was thestrongest when the morphology of the sample was nanosheets, which was very suitable for optical limiting. In addition, dueto the limitation of the application of the sample in the form of solution, we added it into organosilicon, and obtained thesolid antimonene-organosilicon composite with optical limiting function. The results showed that antimonene nanosheetswith best optical limiting ability can be prepared by adjusting the laser irradiation parameters, and the products are successfullyadded into solid matrix to enhance its practicability in protecting people’s eyes and optical equipment from damagecaused by high power laser.
