Abstract
In this communication we analyze exciton annihilation reactions under spatial constraints. Such limitations often lower the effective dimension, an aspect which can be well-modelled through fractals. Thus, qualitative deviations of the reaction pattern from the kinetic scheme occur and allow to highlight the limits of the kinetic approach.
