Abstract
The results of the experiments and modeling suggest that (1) the 0.3-0.45 μm luminescence band is caused mainly by twofold coordinated Pb atoms and partly by threefold coordinated Pb atoms, (2) the 0.5-0.6 μm luminescence band is caused by twofold coordinated Pb atoms, (3) 1.1-1.2 μm IR luminescence band is caused by Pb+ interstitial ions, and (4) 0.85-0.95 and 1.3-1.4 μm IR luminescence bands are caused by complexes formed by interstitial Pb0 atom and a pair of ≡ SiSi ≡ oxygen vacancies.
