Asymmetric dyes align inside carbon nanotubes to yield a large nonlinear optical response

TL;DR: By including an elongated dipolar dye (p,p'-dimethylaminonitrostilbene, DANS, a prototypical asymmetric dye with a strong NLO response) inside single-walled carbon nanotubes (SWCNTs), an ideal head-to-tail alignment in which all electric dipoles point in the same sense is naturally created.
Journal ArticleDOI

Highly sensitive setup for tunable wavelength hyper-Rayleigh scattering with parallel detection and calibration data for various solvents

TL;DR: An extensive set of wavelength-dependent HRS calibration data for a wide range of solvents is presented, and very accurate measurements of the beta dispersion of the well-known nonlinear optical chromophore Disperse Red 1 are demonstrated.
Journal ArticleDOI

First hyperpolarizability dispersion of the octupolar molecule crystal violet: multiple resonances and vibrational and solvation effects.

TL;DR: The first hyperpolarizability (β) dispersion curve is measured for the first time for an octupolar nonlinear optical (NLO) molecule and modeled theoretically, yielding an in-depth understanding of the electronic structure and vibronic and solvation effects on suchOctupolar conjugated systems.
Journal ArticleDOI

Accurate determination and modeling of the dispersion of the first hyperpolarizability of an efficient zwitterionic nonlinear optical chromophore by tunable wavelength hyper-Rayleigh scattering

TL;DR: The wavelength-dependent molecular first hyperpolarizability β of the zwitterionic nonlinear optical (NLO) chromophore picolinium quinodimethane (PQDM) is determined by hyper-Rayleigh scattering (HRS) and used to test and improve theoretical β dispersion models.
Journal ArticleDOI

Rapid, broadband two-photon-excited fluorescence spectroscopy and its application to red-emitting secondary reference compounds

TL;DR: In this paper, a two-channel femtosecond fluorescence excitation apparatus is used to acquire broadband two-photon absorption (2PA) spectra with an estimated accuracy of ± 15% (limited almost exclusively by the uncertainty in the 2PA cross section for the reference standards) over an excitation range of 550-1600 nanometers with a typical time per spectrum of ~30-60 minutes.
