AbstractThe optical spectroscopy (absorption and luminescence) of a small concentration of lead (10 ppm) incorporated into a NaCl:Sr crystal, containing a relatively higher concentration of Sr (350 ppm), has been investigated. For samples annealed at room temperature after quenching, two overlapping absorption bands at 255 and 260 nm grow at the expenses of the A band typical of dissolved Pb2+. For high-temperature (150 and 300°C) annealed samples, the 255- and 260-nm bands grow initially, saturate, and finally decrease for the benefit of another band at 249 nm, which becomes prominent after a long time. The same band is observed in as-grown samples. The luminescence emissions for the various bands have been determined. In the light of the available information, it has been concluded that the 249-nm band corresponds to Pb2+ incorporated into SrCl2 precipitates, whereas the 255- and 260-nm bands should be associated to some intermediate phases, whose structure is not currently known. © 1982 The American Physical Society.
