TL;DR: In this article, Rayleigh scattering spectroscopy is applied to probe the optical transitions of given individual carbon nanotubes in their isolated and bundled forms, and the transition energies of SWNTs are observed to undergo redshifts of tens of meVs.

TL;DR: In this paper, the existence of intrinsic nanoscale lateral p-n junctions in the vicinity of graphene nanobubbles was demonstrated using a charge-transfer heterostructure consisting of graphene.

TL;DR: In this paper, photoluminescence action spectroscopy shows that multiexciton formation is enhanced with increasing optical excitation energy, and this enhancement is attributed to the multieciton formation processes from an electron-hole plasma and results in over 300% more multieexciton emission than at lower excitation energies at 4 K.

TL;DR: In this paper, the influence of buffer layers on the power-dependent time-evolution of photoluminescence in monolayer WSe 2 on different substrates is investigated.

TL;DR: In this article, pump-density-dependent micro-photoluminescence measurements are performed with time-integrating and time-resolving acquisition techniques, showing how radiative decay times strongly differ for different substrate materials.
