Although laser technology brings convenience to production and daily life, it also causes high-energy damage. Therefore, there is an urgent need to develop optical limiting materials for laser protection. In this study, a novel nonlinear optical material, red/black phosphorus lateral heterojunction, is successfully prepared through solvothermal and ultrasonic treatment. Using the Z-scan method, the nonlinear optical properties of the red/black phosphorus heterojunction are determined at wavelengths of 532 and 1064 nm. These results indicate that the red/black phosphorus heterojunction exhibits reverse saturable absorption properties in 1.2.3-glycerol. Interestingly, the red/black phosphorus heterojunction shows an enhanced performance over red phosphorus by introducing the black phosphorus phase. Moreover, the red/black phosphorus heterojunction is doped into organically modified silicate gel glass with excellent broadband optical limiting performance. This study highlights the promising prospect of the red/black phosphorus heterojunction in the nonlinear optical and optical limiting fields.
尽管激光技术给生产和日常生活带来了便利，但它也会造成高能损伤。因此，迫切需要开发用于激光防护的光学限幅材料。在本研究中，通过溶剂热和超声处理成功制备了一种新型非线性光学材料——红磷/黑磷横向异质结。采用Z扫描方法，在532和1064 nm波长下测定了红磷/黑磷异质结的非线性光学性质。这些结果表明，红磷/黑磷异质结在1,2,3-甘油中表现出反饱和吸收特性。有趣的是，通过引入黑磷相，红磷/黑磷异质结比红磷表现出增强的性能。此外，红磷/黑磷异质结被掺杂到具有优异宽带光学限幅性能的有机改性硅酸盐凝胶玻璃中。本研究突出了红磷/黑磷异质结在非线性光学和光学限幅领域的广阔前景。
