Abstract
Luminescence of lead azide Pb(N3)2 crystals in the range of 400-1000 nm is studied experimentally. As the detonation of lead azide is initiated by an electron accelerator pulse, the onset of the mechanical destruction is preceded by intensive luminescence and a rapid growth of the conductivity. Theoretical investigation of the electronic structure of a lead azide crystal was done by means of the Hartree-Fock method for a periodic system. Detailed comparative analysis of the calculated density of states and experimental luminescence spectrum of lead azide suggests that decomposition proceeds by a chain reaction mechanism. A model of the pre-explosive luminescence based on the hypothesis of the quasi-local state formation in the valence band is proposed. The position of a possible energy level of the state in the valence band is predicted. © 2000 Elsevier Science B.V. All rights reserved.
