The spectral-kinetic characteristics of luminescence of PETN with iron nanoparticle inclusions are measured in real time under laser initiation of an explosion (wavelength is 1064 nm, and pulse duration is 14 ns). During the action of the laser radiation pulse, the luminescence of the samples is observed, and explosive decomposition occurs in a microsecond time interval. The spectral pyrometry method is used to establish the thermal nature of explosive luminescence. The explosion temperature is estimated to be 3400±100 K.
