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.

单卡宾链的反斯托克斯拉曼散射

我们研究了限制在双壁碳纳米管内的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的加热。由于其分子尺寸和较大的拉曼横截面，碳炔在局部温度监测方面具有广阔的前景，其潜在应用范围从纳米电子学到生物学。
