1.4K单分子近场光学相干光谱研究
Scanning Near-Field Optical Coherent Spectroscopy of Single Molecules at 1.4 Kelvin
摘要:
我们提出了嵌入在固体基质中的单分子的扫描近场消光光谱。通过改变分子尖端间距,我们修改了光谱的线形,证明了入射激光和分子的激发态之间相互作用的相干性。我们比较了测量数据与数值计算的结果,发现一个非常好的协议。
英文摘要:
We present scanning near-field extinction spectra of single molecules embedded in a solid matrix. By varying the molecule-tip separation, we modify the line shape of the spectra, demonstrating the coherent nature of the interaction between the incident laser light and the excited state of the molecule. We compare the measured data with the outcome of numerical calculations and find a very good agreement.
