Analysis of neodymium rare earth element doping in PbS films for opto-electronics applications

Tuning the Frölich interactions in bismuth modified lead sulphide quantum dots to minimize the excitonic carrier energy dissipation

“…The obtained XRD patterns (Figure 1) of pure PbS and Bi:PbS are exactly coinciding with previously reported diffraction peaks for PbS (JCPDS 05‐0592) 29,30 . The absence of any additional peaks declines the formation of secondary phases (ie, composites) and thus the Bi atoms are exactly doped in the PbS unit cells.…”

“…The obtained XRD patterns (Figure 1) of pure PbS and Bi:PbS are exactly coinciding with previously reported diffraction peaks for PbS (JCPDS 05-0592). 29,30 The absence of any additional peaks declines the formation of secondary phases (ie, composites) and thus the Bi atoms are exactly doped in the PbS unit cells. Two different structures of PbS is identified so far, one with commonly observed rock salt structure (Fm3m space group) and another with zinc blende structure (F43m space group).…”

Use of Anionic Surfactant Sodium Lauryl Ether Sulfate as a Capping Agent in Metal-Chalcogenide PbS Thin Film Production

“…Among the metal-chalcogenide compounds, the lead sulfide (PbS) semiconductor compound has an important place in terms of its properties. We can list these properties as abundance in nature, good chemical stability, high absorption coefficient, high mobility, large exciton Bohr radius, and small band gap [2][3][4]. PbS is a white crystalline solid.…”
