Fractal-like Exciton Kinetics in Membranes, Glasses and Films
Year: 1985
Type: article
Abstract: Fractal-like exciton kinetics were observed in constrained naphthalene samples : 1) Naphthalene embedded in porous glass (vycor) and various porous polymeric (e.g. nylon) membranes. 2) Grain-boundaries inside fresh and annealed naphthalene films formed by rapid, low temperature, vapor deposi tion. 3) Naphthalene embedded in "cavities" of polymeric glasses (e.g. plexiglass). The anomalous exciton annihilation kinetics gives effective spectral dimensions between one and two. Relative contributions of geometric constrains and energetic strains are obtained.
