研究了双壁碳纳米管中单碳炔链的反斯托克斯拉曼散射。使用尖端增强拉曼散射（TERS）识别单个链，并通过不同激光功率的共振激发加热。我们研究了碳炔的拉曼光谱的温度依赖性，并根据反斯托克斯/斯托克斯比量化了激光诱导加热。由于其分子尺寸和大的拉曼截面，碳炔在局部温度监测方面具有很大的前景，其潜在应用范围从纳米电子学到生物学。
We investigate the anti-Stokes Raman scattering of single carbyne chains confined inside double-walled carbon nanotubes. Individual chains are identified using tip-enhanced Raman scattering (TERS) and heated by resonant excitation with varying laser powers. We study the temperature dependence of carbyne's Raman spectrum and quantify the laser-induced heating based on the anti-Stokes/Stokes ratio. Due to its molecular size and its large Raman cross section, carbyne holds great promise for local temperature monitoring, with potential applications ranging from nanoelectronics to biology.
