摘要: Abstract Strongly anisotropic paramagnetic centers produced by X-ray or UV-irradiation of PbCl2 crystals at T = 80 K have been attributed to Pb3+ 2 self-trapped electron (STEL) centers. The self-trapping free (conduction) electrons pure cation sites is further supported production experiments using selective optical excitation in the fundamental absorption band. Optical bleaching suggest STEL center be primary defect responsible for photolysis PbCl2, with g ≈ representing hole-trapped P.A.C.S. numbers: 61.72.Ji; 63.20.Kr; 76.30.Mi; 78.50.Ec; 61.80.Ba, Cb.
