Electronic States and Vibrational Modes of Lead Azide and the Effects Thereon of Photodecomposition.
Abstract
The optical absorption in the ultraviolet and in the near and far infrared of thin films of lead azide have been measured and interpreted. Low temperature luminescence has been discovered. The effects of photodecomposition on the absorption and luminescence have been determined. The effect of doping with charged impurities has been investigated. The dopants are shown to be substitutional and locally charge compensated by native defects. Photodecomposition is shown to occur where the radiation is absorbed, is not diffusion limited and results in destruction of crystallinity during the early stage of decomposition. The material is therefore amorphous during the later, main stage of decomposition. The relevance of these results to initiation and to detonation is noted.
