Study of Structure and Composition of Lead Sulfide ...

Lead sulfide films doped with cadmium and iodine ions were obtained by chemical bath deposition from the reaction mixture with thiourea that have thickness of up to 300 nm. An increase in cadmium iodide in the reactor from 5∙10-5 to 5∙10-3 mol/l is accompanied by a decrease in the period of the B1 cubic crystal lattice (space group ) from 0.59368 to 0.59355 nm, due to the

Heterogeneous lead isotopic compositions of sulfide ...

2020-7-1 · 1. Introduction. The isotopic evolution of lead (Pb) over Earth's history has been studied for almost a century. The first quantitative model that could accurately match the Earth’s age and average isotopic composition was proposed by Houtermans (1953).His evolutionary model was strongly simplified, as it assumed that Earth evolved from a single closed reservoir.
