Photoproduction of Disorder in PB(N3)2 and TIN3
Abstract
Pb Tl, and other inorganic azides have been exposed to ultraviolet and X-ray irradiation, and the resulting changes in optical properties have been studied. This irradiation was found to produce a structureless increase in extinction, which increases in magnitude with decreasing wavelength to the band edge. Calculations for Pb(N3)2 indicate that the wavelength dependence of this irradiation-induced extinction is what might be expected from colloidal lead. The increased extinction is insensitive to the temperature of observation, and diffuse reflectance measurements indicate that some part, if not all of it, is due to absorption. Both of these results are to be expected if the extinction is due to colloidal lead. Essentially the same type of extinction is obtained for ultraviolet and X-ray irradiation at sample temperatures of 12 degrees, 78 degrees, and about 300 degrees K, and also for decomposition produced solely by thermal means. Some differences between Pb(N3)2 and TlN3 are discussed.
