Abstract

Persistent spectral hole burning (HB) is now in use for about fifteen years in the investigation the low-temperature dynamics of condensed organic materials [1-3]. It is well established that the hole width is very sensitive to matrix structure. In particular, a striking difference is found between crystals, where the holes are broadened according to the activation of a libration mode, and glasses or polymers where the temperature dependence is much slower (of the type Tα, 1≤ α ≤ 2) [4]. This behavior has been attributed to the broad spectrum of the specific low-energy excitations of glasses known as two-level-systems (TLS). The study of new ‘exotic’ matrices for dopant dye molecules may on the one hand bring valuable information on the dynamics and structure of these systems as compared to more conventional phases, on the other hand help us shed light on the mechanisms behind dephasing and spectral diffusion.
