Initial distribution of geminate electron—hole pairs produced by two-photon ionization in poly(methyl methacrylate)

The initial distribution of photoejected electrons produced by two-photon excitation of aromatic amines doped in poly-(methyl methacrylate) bulk was analyzed. Experimental observed ion decays were well simulated by a long-range electron-transfer mechanism with a far-Gaussian distribution function of the ejected electrons with its maximum at ≈ 30 Å from the parent radical cation.
