Solution-processed lead sulfide quantum dots (PbS QDs) are an excellent candidate for photodetector applications because they exhibit broadband absorption, a wide range of tuneable bandgaps, high stability in air, and mechanical flexibility. However, crucial criterion the fabrication high-performance photodetectors is selection ligands, which can facilitate charge carrier transport between PbS ...

A series of lead(ii) alkylxanthates, [Pb(S2COR)2] (R = ethyl (1), n-propyl (2), n-butyl (3), n-hexyl (4) or n-octyl (5)) have been prepared and explored as single source precursors for use in melt reactions to form lead sulfide. X-ray single crystal structures of (2), (3) and (4) were used along with previously reported structures to investigate the influence of structure and chain length on th...

In this study, the (Lead Sulfide) PbS thin films with one, two, and three layers were fabricated by employing chemical bath deposition method. Layer layer production of was realized for first time as seen in literature review. For investigating crystal structures, X-ray diffraction (XRD) analysis used. The structural analyses indicated that crystallite size decreased from about 40 nm to 8-10 de...

Fully solution-processed, large-area, electrical double-layer transistors (EDLTs) are presented by employing lead sulfide (PbS) colloidal quantum dots (CQDs) as active channels and Ti3C2Tx MXene contacts (including gate, source, drain). The successfully patterned standard photolithography plasma-etch techniques integrated with CQD films. large surface area of film is effectively gated ionic gel...

We investigate the low temperature electron transport properties of manganese doped lead sulfide films. The system shows variable range hopping at low temperatures that crosses over into an activation regime at even lower temperatures. This crossover is destroyed by an applied magnetic field which suggests a magnetic origin of the hard gap, associated with bound magnetic polarons. Even though t...

As a well-known toxic pollutant, sulfide is harmful to human health. In this study, a simple and sensitive amperometric inhibitive biosensor was developed for the determination of sulfide in the environment. By immobilizing nanoporous gold (NPG) on glassy carbon electrode (GCE), and encapsulating horseradish peroxidase (HRP) onto NPG, a HRP/NPG/GCE bioelectrode for sulfide detection was success...

This paper mainly investigated the synthesis of a high purity PbS crystal directly from lead ash which was collected Tin removal process (LATR). The LATR firstly disposed by nitric acid leaching system to generate nitrate solution. prepared mixing solution with sodium sulfide at room temperature (25?C). effects molar ratio HNO3 Pbin on Pb efficiency investigated, demonstrating that could attain...

Hydrogen sulfide (H2S) is an important biological messenger, but few biologically-compatible methods are available for its detection in aqueous solution. Herein, we report a highly water-soluble naphthalimide-based fluorescent probe (L1), which is a highly versatile building unit that absorbs and emits at long wavelengths and is selective for hydrogen sulfide over cysteine, glutathione, and oth...

in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...
