High Infrared Photoconductivity in Films of Arsenic-Sulfide-Encapsulated Lead-Sulfide Nanocrystals
Highly photoconductive thin films of inorganic-capped PbS nanocrystal quantum dots (QDs) are reported. Stable colloidal dispersions of (NH4)3AsS3-capped PbS QDs were processed by a conventional dip-coating technique into a thin homogeneous film of electronically coupled PbS QDs. Upon drying at 130 °C, (NH4)3AsS3 capping ligands were converted into a thin layer of As2S3, acting as an infrared-tr...
متن کاملSingle-step synthesis of silver sulfide nanocrystals in arsenic trisulfide
Silver sulfide nanocrystals and chalcogenide glasses (ChGs) are two distinct classes of semiconductor materials that have been exploited for new infrared technologies. Each one exhibits particular optoelectronic phenomena, which could be encompassed in a hybrid material. However, the integration of uniformly distributed crystalline phases within an amorphous matrix is not always an easy task. I...
متن کاملSubstrate Effects on the Structural Properties of Thin Films of Lead Sulfide
Nanocrystalline PbS thin films are deposited on glass and alumina substratesthrough the chemical bath deposition technique by creating similar conditions, in orderto investigate the effects of the substrate. The structural and optical properties of PbSfilms are investigated by X-ray diffraction, scanning electron microscope, and UV–Vis.The structural analyses of the films indicate that they are...
متن کاملDirect synthesis of high-density lead sulfide nanowires on metal thin films towards efficient infrared light conversion.
We report chemical-vapor-deposition (CVD) synthesis of high-density lead sulfide (PbS) nanowire arrays and nano pine trees directly on Ti thin films, and the fabrication of photovoltaic devices based upon the PbS nanowires. The as-grown nanowire arrays are largely vertically aligned to the substrates and are uniformly distributed over a relatively large area. Field effect transistors incorporat...
