Abstract

The first results of an investigation into the spectral and kinetic characteristics of a pulsed cathodoluminescence from polycrystalline heavy metal azides at an excitation level below the explosion initiation threshold are presented. It is established that the emission from AgN3, PbN6, and TlN3 at 300 K measured in the interval of quantum energies from 1.5 to 3.5 eV represents weakly structured broad bands limited by the fundamental absorption edge of each material, with a characteristic decay time of τ < 20 ns. At 30 K, TlN3 exhibits luminescence in the interval from 1.5 to 2.5 eV with a maximum at 1.85 eV decaying on a microsecond time scale. The temperature dependence of the spectral and kinetic parameters of emission was studied.
