Properties of Colloidal Disorder in Small Band Gap Azides

Properties of Colloidal Disorder in Small Band Gap Azides 

In this section the properties of colloidal disorder in Pb(N3)2 and TIN3 are reviewed. Similar measurements for AgN3 have not been made. 

Examination of UV-irradiated Pb(N3)2 and TIN3 under a low-power microscope revealed that the disorder is not uniformly distributed through samples upon uniform irradiation [7,8,59]. Disorder may be significantly greater in 

Section E). Samples mounted in this vacuum system did not show significant changes of optical extinction on warming to room temperature after irradiation at about 80°K, and large pressure increases ( 10 torr) were also not observed. However, significant decreases of the optical extinction were found when the pressure was allowed to increase by purposely admitting air. 

The optical extinction can be partially bleached under some conditions [59,104]. If UV irradiation is followed by exposure for an appropriate length
