Femtosecond photon echo spectroscopy of semiconducting single-walled carbon nanotubes.
Three-pulse photon echo peak shift measurements were performed on semiconducting single-walled carbon nanotubes embedded in polymer matrix at room temperature. Simultaneous modeling of the peak shift data in the limit of zero-intensity and the linear absorption spectrum enable us to extract an intrinsic homogeneous line width of 178 cm(-1), an inhomogeneous width of 698 cm(-1), and a Huang-Rhys...
متن کاملTwo-color three pulse photon echo peak shift spectroscopy
Two-color three pulse photon echo peak shift spectroscopy ͑2C3PEPS͒ has been used to probe correlation in electronic transitions in two different regions of the electronic spectrum of a chromophore in the condensed phase. The 2C3PEPS can be done in an ''uphill'' or a ''downhill'' sense, where the first two interactions are of lower ͑higher͒ frequency than the final interaction with the radiation fi...
متن کاملFemtosecond Photon Echo Spectroscopy in Single Laser Shot
We take advantage of extreme spatial thinness of 100-femtosecond pulse of an amplified femtosecond laser and measure for the first time the homogeneous spectrum of a strongly inhomogeneously-broadened solid with a single laser shot. This is achieved by combining causality-related diffraction asymmetry of twoand three-pulse photon echo with oblique excitation pulse wave fronts, which are creatin...
متن کاملEnergy transfer in organic systems X . Pure and mixed crystals
Expressions are derived for the host and guest fluorescence response functions and quantum yields of thin and thick, pure and mixed organic crystals. I n addition to exciton migration and transfer, the effects of host exciton traps and of radiative migration and transfer are considered. Host exciton traps and radiative migration are shown to be important in thick anthracene and mixed anthracene...
متن کاملOrganic semiconductor co-crystals: reactivity, mobility, and spectroscopy
Organic semiconductors are of interest because low processing temperatures and cost which make such materials candidates for flexible electronics. The charge transport properties of the material are largely dependent on solid-state arrangement of the molecules. This thesis focuses on co-crystallization as a means to achieve [2+2] photodimerization with organic semiconductors, the impact the co-...
