Abstract Antimonene and antimonene oxides were prepared by laser irradiation in different solvents, including deionized water, ethanol and isopropanol. The results showed that isopropanol was proven to be more suitable for preparing high-quality antimonene with good dispersion and slight surface oxidation, which was probably attributed to its chain length and no reaction with antimony under laser irradiation. In addition, open aperture and closed aperture Z-scan experiments were carried out to study the optical limiting properties of antimonene. It was observed that antimonene prepared in isopropanol exhibited stronger optical limiting ability with a NLO absorption coefficient βeff of ~2.00 cm/GW and a positive nonlinear refraction index n2 of ~1.10 × 10−13 cm2/W, making it a good candidate for applications in optical limiting devices and laser protection.

不同溶剂中激光辐照制备锑烯用于光限幅

摘要 在去离子水、乙醇和异丙醇等不同溶剂中，通过激光照射制备了锑烯和氧化锑烯。结果表明，异丙醇更适合制备具有良好分散性和轻微表面氧化的高质量锑烯，这可能是由于其链长且在激光照射下与锑不发生反应。此外，还进行了开孔和闭孔Z扫描实验以研究锑烯的光学限制特性。观察到在异丙醇中制备的锑烯表现出更强的光学限制能力，NLO 吸收系数 βeff 为~2.00 cm/GW，正非线性折射率 n2 为~1.10 × 10−13 cm2/W，
