- 中文摘要: Trapped electrons, eg¯, are produced by photoionization of K4Fe(CN)6 in 10M NaOH/H2O and 10M NaOD/D2O glasses at 4.2°K. The linewidth, ΔHms, of eg¯ changes reversibly between these two temperatures in contrast to the observations for organic matrics. Three proposed mechanisms including dipole relaxation of pendent molecules surrounding the electron cavity, contraction-expansion model of cavity, and electron retrapping process are each discussed. It appears that no one physical model satisfactorily accounts for the present observations. The electron retrapping process, however, might be a better candidate for interpreting the experimental results in compatible with the optical absorption data.
