Abstract : Many Persistent spectral hole-burning (PSHB) experiments on various organic glasses and polymers doped with organic molecules reveal that the temperature dependence Of the homogeneous linewidth (tau h) is T1.3 at low temperature (0.3 K - 20 K). In contrast to organic molecules, very few PSHB data exist for rare earth ions in inorganic materials while data by fluorescence line-narrowing (FLN) above approx. 1OK are considerably accumulated. Macfarlane and Shelby observed PSHB in Pr3+- and Eu3+ -doped silicate glasses and reported that tau h of them have a T1.0 dependence. Similar results were obtained by Van der Zaag et al. In pure crystals, tau h is theoretically expected to have a T7 - dependence in the low temperature region and a T2 - dependence above the Debye temperature (Raman process).
