Abstract

Until now, in spite of a great number of experimental and theoretical works in study of organic amorphous solids, the basic features of the low temperature dynamics of these mediums are poorly understood. One of the main reason of this is the lack of experimental information about these dynamical processes. In particular, it’s necessary to learn more about optical dephasing in doped organic glasses and polymers for wider temperature interval. It will allow to test the existent theories more correctly and to create new conceptions.

The principles of incoherent photon echoes (IPE) are shortly recalled. The results on dynamics in doped organic glasses and polymers (resorufin in d‐ and d6‐ethanol and terrylene in polyethylene) studied by IPE are presented. In all cases the fast dephasing processes are related to coupling with both two‐level systems (TLS) and pseudolocal mode. The nanosecond spectral diffusion (SD) processes has been observed. The IPE‐results are compared with hole‐burning and single molecule spectroscopy (SMS) data.

PHOTON-ECHO STUDY OF ULTRAFAST DEPHASING IN AMORPHOUS SOLIDS IN WIDE TEMPERATURE REGION WITH INCOHERENT LIGHT

The temperature-dependence of the electronic dephasing for resorufin in d-ethanol glass was measured from 1.7 to 35 K by incoherent photon echo. The difference between two-pulse picosecond photon echo and incoherent photon echo results was obtained and attributed to spectral diffusion in nanosecond time scale.

Low temperature dynamics in amorphous solids: A photon echo study

Hans C. Meijers, Douwe A. Wiersma

The long-lived stimulated photon echo is put forward as a powerful technique to probe structural dynamics in glasses and other amorphous solids. We present results of optical dephasing measurements on several doped organic glasses (deuterated ethanol, toluene, and triethylamine) and polymers (polystyrene, polyvinylbutyral, and polymethylmethacrylate). Using a stochastic analysis within the so-called two-level-system model, we can extract from these measurements the distribution function of fluctuation rates over a huge range of time scales, varying from picoseconds to hundreds of milliseconds. We show that the dynamics, which lies at the origin of spectral diffusion, is very dependent on the glass structure and can be described by two separate hyperbolic distribution functions of fluctuation rates. From longitudinal photon echo measurements in the population dimension, we find evidence for structural dynamics which is not accounted for in the standard two-level-system model and which is related to a spatially inhomogeneous distribution of fluctuation centers.

Ultrafast dephasing of Resorufin in d-ethanol glass from 17 to 40 K studied by incoherent photon echo

N.V. Gruzdev, Силькис Эммануил Гершович, V. D. Titov +1 more

The temperature dependence of the electronic dephasing of Resorufin in d-ethanol glass was measured from 1.7 to 40 K by incoherent photon echo (IPE) techniques. At T = 8–11 K good agreement between IPE and two-pulse picosecond photon echo (PPE) results was observed. For T < 8 K, PPE and IPE results differed; the difference is attributed to spectral diffusion on a nanosecond time scale. IPE results for T > 11 K confirm the hypothesis that high-temperature dephasing in this system is due mainly to interaction with a pseudolocal mode.
