Abstract

Small crystallites of PbCl₂ have been observed on Cl_2- and air-exposed surfaces of PbS. Identification has been made by observing the fundamental exciton of PbCl₂ in thermoreflectance, and by the EDAX technique in a scanning electron microscope. Similar effects occur on PbSe and PbTe. The phenomenon may be applicable to a low level integrating chlorine detector.
