|
|
| Strongly anisotropic paramagnetic centers produced by X-ray or UV-irradiation of PbCl2 crystals at T = 80 K have been attributed to Pb-2(3+) self-trapped electron (STEL) centers. The self-trapping of free (conduction) electrons at pure cation sites is further supported by production experiments using selective optical excitation in the fundamental absorption band. Optical bleaching experiments suggest the STEL center to be the primary defect responsible for the photolysis in PbCl2, with the g approximate to 2 centers representing hole-trapped centers. |
