Fractal-Like Exciton Kinetics in Porous Glasses, Membranes and Powderse yields the dynamic (spectral, fracton) dimension of the embedded naphthalene structure or the effective random walk dimension of the porous network. Temperature studies separate the energetic and geometric features of the pore space. The geometric dynamic (spectral) dimensions are mostly between 1

Reaction Kinetics on Fractal and Euclidean Structures with Energetic Disorder: Random Walk Simulatios performed on the Cyber 205 supercomputer for the elementary reaction A + A → A show that the rate law is well described in terms of the microscopic exploration space of a single random walker, that is, by the number of distinct sites visited, S. This provides a scaling approach for moving from sin

Dynamical Hole-Burning Requirements for Frequency Domain Optical Storage of persistent spectral hole-burning to form a frequency domain optical storage system [1]–[5] . PHB (also called photochemical hole-burning although photophysical hole-burning also occurs) has the interesting property of allowing as many as 1000 or more bits of information to be stored in the volum

Exciton Transport in Naphthalene-Doped Poly (Methylmethyl-Acrylate): Spatial and Energetic Disorderphorescence and delayed fluorescence spectra and their decay dynamics are studied in a “plexiglass” sample that is both mechanically improved and optically activated via doping with aromatic molecules (naphthalene, anthracene). The dopants are aggregated in sub-microscopic domains (“cavities”, “pore

On Electron Transfer Reactions in Disordered Mediadiscuss the main qualitative features of these processes. Electron transfer reactions in the gas phase are reasonably well understood. In some cases the reaction is direct; in others it involves the formation of an unstable quasimolecule (of lifetime 10.sec) posessing a full set of quantum numbers..

Time-Resolved Dielectric Loss as a Probe of Interfacial Electron Transfer Dynamicsof light by the semiconductor promotes an otherwise thermodynamically favored process, is the generation of electrons and positive holes in the semiconductor. These carriers can then react with the dispersion solvent or a reagent dissolved therein (1–3). The dynamics of the interfacial electron tran
