Abstract

When materials are deformed and fractured, new surfaces are formed which may contain charge concentrations, defects, and broken bonds. The consequences of such departures from non-equilibrium can be the emission of particles (electrons, ions, and neutral species) as well as photons (triboluminescence). Collectively, we refer to these emissions as fracto-emission. In the case of peeling pressure sensitive adhesives from various substrates, charge separation plays a dominant role in producing relatively intense photon-emission as well as other emissions. Here we report on a few of the properties of the photon emission from peeling commercial adhesive tapes and address in particular the time, spectral, and spatial domains.
