Two-dimensional (2D) sheets of antimonene have attracted increasing attention due to their unique physical and chemical properties prompting potential for diverse applications. We present a facile method to prepare high-quality antimonene nanosheets (ANSs) by micromechanical exfoliation on SiO₂/Si substrate. The temperature- and laser power-dependent Raman studies of exfoliated ANSs are reported and analyzed. It was found that both the out-of-plane A_1g and the in-plane E_g modes red-shift linearly with increase in temperature, pointing towards anharmonic vibrations of the lattice. The thermal response of the ANSs on a SiO₂/Si surface is also described using numerical simulation of the heat transfer to study their laser-induced oxidation mechanisms. These results offer a deeper understanding of the phonon properties and oxidation susceptibility of 2D antimonene paving the way for the development of antimonene-based technologies, such as electronic devices or photothermal cancer therapy.

二维（2D）锑锭片因其独特的物理和化学性质而引起了越来越多的关注，这提示了其在各种应用中的潜力。我们提出了一种简便的方法，通过在SiO ₂ / Si基底上进行微机械剥离来制备高质量的锑烯纳米片（ANSs）。剥落的ANS的温度和激光功率依赖性拉曼研究得到报道和分析。已经发现，平面外的A _1g和平面内的E _g都随着温度的升高而线性地红移，这指向晶格的非谐振动。ANS ₂在SiO ₂上的热响应还使用传热的数值模拟来描述/ Si表面，以研究其激光诱导的氧化机理。这些结果使人们对2D锑的声子特性和氧化敏感性有了更深入的了解，为基于锑的技术（例如电子设备或光热癌症疗法）的发展铺平了道路。
