Abstract

Time-resolved hole-burning (HB) experiments have been performed on the S₁←-S₀ 0-0 transitions of free-base chlorin in polystyrene (H₂Ch in PS) and bacteriochlorophyll-a in triethylamine (BChl-a in TEA) as a function of temperature (1.2 4.2 K), excitation wavelength, concentration, and delay time between burning and probing. At concentrations higher than 5×10^-4 M a new type of spectral diffusion process takes place, even at T→0, which is induced by energy transfer. Moreover, HB-experiments on BChl-a in TEA with delay times between microseconds and hours at high (Δp≈30 kbar) pressure demonstrate that a transition from a glassy- to a locally ordered structure occurs in this sample, suggesting that the number of `two-level-systems' in the glass responsible for spectral diffusion is reduced by compression.
