Y. Ichino et al., UNIVERSALITY IN VIBRATIONAL-MODES OF VARIOUS DISORDERED MATERIALS EXAMINED BY HOLE-BURNING-FREE FLN SPECTROSCOPY, Journal of luminescence, 66-7(1-6), 1995, pp. 358-361
Site-selective excitation spectroscopy has been performed for various
dye-doped disordered materials which tend to suffer from hole-burning.
The densities of states for low-frequency vibrational modes of the ho
sts, weighted by the electron-phonon interaction strength, have been d
etermined and show a universal feature when the scales are normalized.
