Effect of phonon-induced desorption of oxygen molecules from the surface of a solid on adsorbate luminescence kinetics

Abstract

A mathematical model to describe the pulse shape of delayed adsorbate fluorescence is proposed that accounts for desorption of oxygen molecules from the surface of a substrate induced by interaction with phonons. A numerical study of the temperature dependence of the probability of desorption of oxygen molecules from the substrate surface and of the luminescence intensity is carried out.
