The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

In the 60 years since the invention of the laser, the scientific community has developed
numerous fields of research based on these bright, coherent light sources, including the …

Large binding energy and unique exciton fine structure make the transition metal
dichalcogenides (TMDCs) an ideal platform to study exciton behaviors in two-dimensional …

The defining characteristic of a nanomaterial is that its properties vary as a function of its
size. This size dependence can be clearly observed in single-walled carbon nanotubes …

Optical microscopy, the simultaneous acquisition of spectroscopic and spatial information
using light, forms the basis of many natural sciences. In this chapter, we review a novel …

Photoluminescence quantum yields and nonradiative decay of the excitonic S1 state in
length fractionated (6, 5) single-wall carbon nanotubes (SWNTs) are studied by continuous …

Abstract Knowledge of excited-state dynamics in carbon nanotubes is determinant for their
prospective use in optoelectronic applications. It is known that primary photoexcitations are …

Single-wall carbon nanotubes (SWCNT) fluoresce in the near-infrared (NIR) region and
have been assembled with biopolymers such as DNA to form highly sensitive molecular …

Thin film networks of highly purified semiconducting carbon nanotubes (CNTs) are being
explored for energy harvesting and optoelectronic devices because of their exceptional …

Upon absorption of single photons, multiple excitons were generated and detected in
semiconducting single-walled carbon nanotubes (SWNTs) using transient absorption …
