“…Among the chemical methods, chemical bath deposition (CBD) is of special interest because it is simple, but highly efficient. This method has been successfully used for the deposition of macrocrystalline PbS (film with an average grain size of 200-300 nm) with excellent photoconductive properties for application in IR detectors [4]. CBD allows potent and adjustable control of the size and surface density of nanoparticles, and can be used for preparation of high-quality nanocrystalline PbS film.…”

PbS nanocrystalline thin film was prepared by chemical bath deposition on Si (1 0 0) substrate at bath temperatures of 25, 45 and 65°C. Triethanolamine was added to the aqueous solution, which decreased the grain size and increased the luminescence of the nanocrystalline PbS thin film. PbS nanocrystals were identified using XRD, TEM and AFM. The crystalline size of the PbS film deposited at different bath temperatures was estimated by XRD and TEM to be 7-12 nm. The growth mechanism of the PbS crystallites were described at different bath temperatures. The confinement was reflected in the absorption spectra, photoluminescence excitation and photoluminescence spectra. The luminescence of Si(1 0 0) substrate and PbS nanocrystalline film deposited on Si(1 0 0) were compared, and the results revealed that the PbS nanocrystals altered and notably enhanced the emission features of the Si(1 0 0) substrate. The shifting of the maximum photoluminescence emission wavelength of PbS nanocrystals with a change in bath temperature and the variation in photoluminescent intensity of PbS nanocrystals prepared at 25°C versus deposition time were investigated. A single-peak fit of a Gaussian function was employed to discern the photoluminescence of PbS on Si(1 0 0) substrate.

“…Both CdS and PbS are important photoconductors and due to their technological applications have drawn interest of research workers, particularly using chemical deposition technique. A number of research workers [1][2][3] prepared PbS films using different substrates like dielectrics/ ferroelectrics and semiconducting materials etc. A large number of workers [4][5][6][7] also prepared CdS films by such a technique.…”

The results of photoconductivity (PC), photoluminescence (PL), optical absorption spectra, XRD and SEM studies are presented for (Cd 0.95 -Pb 0.05 )S : CdCl 2 ,Ce films prepared by chemical bath deposition technique. PC gains ~10 7 are found in doped films. PL emission spectrum is found in red region which is related to 5d to 4f transition in Ce. Films prepared at 60°C show better PC while those prepared at room temperature (RT) show better PL. Optical absorption studies show reduction in band gap due to addition of PbS. A peak due to Ce is also observed in absorption spectrum. XRD studies show the presence of both CdS and PbS. SEM studies show presence of microcrystals, cluster of grains along with some rod type structures.
