Enhancement of physical properties of nebulizer spray-pyrolyzed PbS thin films for Optoelectronic device application: an effect of Ag doping

Pioneering method for the synthesis of lead sulfide (PbS) nanoparticles using a surfactant-free microemulsion scheme

“…1 PbS is a group IV-VI binary element with a low band gap, large exciton Bohr radius (18 nm), extreme quantum connement, high carrier mobility, low thermal conductivity, and other properties, which make strong quantization effects visible even for large particles or crystallites. 3 Hence, it is a promising candidate to play an active role in various optoelectronic devices, such as infrared photodetectors, 4 solar cells, [5][6][7][8] infrared light-emitting diodes (LEDs), 9 thermoelectric cells, 10 near-infrared light-emitting eld-effect transistors, 11 and llers in polymer nanocomposites, 12 and other elds such as telecommunications and biomedical applications. 3 Usually, chemical routes are preferred for the synthesis of nanostructures owing to the simplicity and availability of many controlling key parameters.…”
