Journal ArticleDOI
Chemical mapping of a single molecule by plasmon-enhanced Raman scattering
Rui Zhang,Yao Zhang,Zhen-Chao Dong,Song Jiang,Cheng Zhang,L. G. Chen,Lixin Zhang,Y. Liao,Javier Aizpurua,Yi Luo,Yi Luo,Jinlong Yang,Jianguo Hou +12 more
TL;DR: Raman spectral imaging with spatial resolution below one nanometre is demonstrated, resolving the inner structure and surface configuration of a single molecule by spectrally matching the resonance of the nanocavity plasmon to the molecular vibronic transitions, particularly the downward transition responsible for the emission of Raman photons.
Journal ArticleDOI
Visualizing coherent intermolecular dipole–dipole coupling in real space
Yang Zhang,Yang Luo,Yao Zhang,Yun-Jie Yu,Yanmin Kuang,Li Zhang,Qiushi Meng,Yi Luo,Jinlong Yang,Zhen-Chao Dong,Jianguo Hou +10 more
TL;DR: The experimental approach provides detailed spatial information about coherent dipole–dipole coupling in molecular systems, which should enable a greater understanding and rational engineering of light-harvesting structures and quantum light sources.
Journal ArticleDOI
Generation of molecular hot electroluminescence by resonant nanocavity plasmons
Zhen-Chao Dong,Xian-Biao Zhang,Hong-Ying Gao,Yi Luo,Cheng Zhang,Luo-Kan Chen,Rui Zhang,Xiaoming Tao,Yang Zhang,Jinlong Yang,Jianguo Hou +10 more
TL;DR: In this paper, the effect of resonant hot electroluminescence arising directly from higher vibronic levels of the singlet excited state (S1(v′−>−0) for porphyrin molecules confined inside a nanocavity in a scanning tunnelling microscope, by spectrally tuning the frequency of plasmons was demonstrated.
Journal ArticleDOI
Distinguishing adjacent molecules on a surface using plasmon-enhanced Raman scattering
Song Jiang,Yao Zhang,Rui Zhang,Chun-Rui Hu,Menghan Liao,Yi Luo,Jinlong Yang,Zhen-Chao Dong,Jianguo Hou +8 more
TL;DR: Two different adjacent molecules that are within van der Waals contact and of very similar chemical structure on a silver surface can be distinguished in real space using a nonlinear scanning tunnelling microscope-controlled TERS set-up.
Journal ArticleDOI
Vibrationally resolved fluorescence from organic molecules near metal surfaces in a scanning tunneling microscope.
Zhen-Chao Dong,X. L. Guo,Artem S. Trifonov,Pavel S. Dorozhkin,Kazushi Miki,K. Kimura,Shiyoshi Yokoyama,S. Mashiko +7 more
TL;DR: Intrinsic molecular fluorescence from porphyrin molecules on Au(100) has been realized by using a nanoscale multimonolayer decoupling approach with nanoprobe excitation in the tunneling regime, suggesting an excitation mechanism via hot electron injection from either tip or substrate.
