The electronic dephasing times of a chromophore, oxazine 4 (Ox4), doped in low temperature saccharide glasses were investigated by femtosecond photon echo spectroscopy. It was revealed that the dephasing time is much longer in the saccharide glasses compared to hydrogen bonding polymer glass, polyvinylalcohol (PVA), when temperature was lowered to 10 K. A critically damped low frequency oscillation was observed in the signal which can be attributed to the phonon mode of the saccharide glass. The electronic coherence is preserved in the low-temperature saccharide glass due to the restraint thermal fluctuation.
