Tip-induced excitonic luminescence nanoscopy of an atomically-resolved van der Waals heterostructure
Low-temperature scanning tunneling microscopy is used to probe, with atomic-scale spatial resolution, the intrinsic luminescence of a van der Waals heterostructure, made of a transition metal
Internal Stark effect of single-molecule fluorescence
The optical properties of chromophores can be efficiently tuned by electrostatic fields generated in their close environment, a phenomenon that plays a central role for the optimization of complex
Evidence of trion-libron coupling in chirally adsorbed single molecules
Interplay between motion of nuclei and excited electrons in molecules plays a key role both in biological and artificial nanomachines. Here we provide a detailed analysis of coupling between
Control of molecular orbital ordering using a van der Waals monolayer ferroelectric
Two-dimensional (2D) ferroelectric materials provide a promising platform for the electrical control of quantum states. In particular, due to their 2D nature, they are suitable for influencing the
Cavity-Modulated Proton Transfer Reactions.
Proton transfer is ubiquitous in many fundamental chemical and biological processes, and the ability to modulate and control the proton transfer rate would have a major impact on numerous quantum

Ultraresolution microscopy far beyond the classical Abbe diffraction limit of one half wavelength (λ/2), and also beyond the practical limit (ca. λ/10) of aperture–based scanning near–field optical microscopy (SNOM), and theoretical modelling that explains and predicts s–SNOM contrast on the basis of the local dielectric function is described.
Atomic-Scale Structural Fluctuations of a Plasmonic Cavity
This work investigates the influence of a controlled single-atom transfer from the tip to the sample on the plasmonic properties of the junction and forms a well-defined atomic contact of several quanta of conductance to observe changes of the electroluminescence intensity.
The 2015 super-resolution microscopy roadmap
Far-field optical microscopy using focused light is an important tool in a number of scientific disciplines including chemical, (bio)physical and biomedical research, particularly with respect to the
Tip-enhanced near-field optical microscopy.
This review illustrates the physical principle of TENOM that utilizes the antenna function of a sharp probe to efficiently couple light to excitations on nanometer length scales and discusses the antenna-induced enhancement of different optical sample responses including Raman scattering, fluorescence, generation of photocurrent and electroluminescence.
Sub-nanometre resolution in single-molecule photoluminescence imaging
Ambitions to reach atomic resolution with light have been a major force in shaping nano-optics, whereby a central challenge is achieving highly localized optical fields. A promising approach employs
Sub-nanometre control of the coherent interaction between a single molecule and a plasmonic nanocavity
Sub-nanometre spatial control over the coherent coupling between a single molecule and a plasmonic nanocavity in close proximity is demonstrated by monitoring the evolution of Fano lineshapes and photonic Lamb shifts in tunnelling electron-induced luminescence spectra.
Visualizing vibrational normal modes of a single molecule with atomically confined light
The vibrational normal modes in a single molecule are imaged using tip-enhanced Raman spectromicroscopy performed in the atomistic near-field, and ångström-scale resolution is attained at subatomic separation between the tip atom and a molecule in the quantum tunnelling regime of plasmons.
Radiative control of dark excitons at room temperature by nano-optical antenna-tip Purcell effect
Tip-enhanced photoluminescence spectroscopy allows for modulation and radiative control of dark exciton emission at room temperature, and provides a facile way to harness excitonic properties in low-dimensional semiconductors offering new strategies for quantum optoelectronics.
Ordinary and Hot Electroluminescence from Single-Molecule Devices: Controlling the Emission Color by Chemical Engineering.
Single-molecule junctions specifically designed for their optical properties are operated as light-emitting devices using a cryogenic scanning tunneling microscope to generate a narrow-line emission of light whose color is controlled by carefully selecting the chemical structure of the emitting unit.
