Polycrystalline nanostructured PbS thin ﬁlms are deposited onto soda-lime glass substrates by the method of chemical bath deposition (CBD) at different duration of deposition time. The structure and surface morphology of the ﬁlms are characterized by X-ray diﬀraction (XRD) and field effect scanning electron microscopy (FE-SEM). XRD pattern exhibits polycrystalline structure with preferential orientation along (200) direction, parameters such as crystallite size, lattice constant, lattice-strain and dislocation density are calculated. The FE-SEM images show appearance of flower like structure on formation of PbS films which is indicative of suitability in gas sensing applications. Studies on optical properties carried out by UV-Vis spectroscopy measurements show bandgap in the range 1.65eV – 1.41eV. The photoluminescence spectra of the films exhibit two peaks centered at around 613 nm and 738 nm after excitation at 450 nm. Electrical studies from Hall measurements indicate the carrier concentration and mobility of the PbS samples corroborate the variations in the conductivity.

“…It is well known that among different preparation techniques such as SILAR [10], Sputtering [11], Spray Pyrolysis [12] etc. the method of chemical bath deposition (CBD) is the most inexpensive technique for PbS thin films which is based on the reaction of the species on the substrate surface from aqueous solutions [13,14].…”

Pure and Pb‐doped MnS thin films are prepared by chemical bath deposition (CBD) method onto glass substrates at 60 °C temperature. The films are characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray analysis, and optical absorption spectroscopy. The particle size of the crystalline is determined from the XRD patterns using Scherrer formula and is 47 nm for MnS thin films. The particle size shows a change in the case of the Pb‐doped film. The optical band gap of MnS thin film is found to be 3.1 eV, which decreases on doping with Pb. SEM graphs of doping of Pb in MnS confirmed the formation of spherical superstructure and indicate that the Pb2+ is successfully substituted into the MnS host structure of the Mn2+ site.

“…These attributes are all determined by morphology, surface properties, crystal defects, phase and size, which rely completely on their synthetic methods. PbS nanostructures have been prepared using different methods such as chemical deposition [9], hydrothermal [10], microwave/sonochemical [11], thermal decomposition [12] and sol-gel [13]. Many researchers have investigated the ferroelectric, dielectric and electrical properties of PbS formed by various synthetic techniques.…”

Nanostructured Lead Sulphide Depositions by AACVD Technique Using Bis(Isobutyldithiophosphinato)Lead(II) Complex as Single Source Precursor and Its Impedance Study

This communication reports the synthesis of bis(diisobutyldithiophosphinato)lead(II) complex and its subsequent application as a single source precursor for the nanostructured deposition of lead sulphide semiconductors and its impedance to explore its scope in the field of electronics. Synthesized complex was characterized by microelemental analysis, nuclear magnetic resonance spectroscopy, infrared spectroscopy and thermogravimetric analysis. This complex was decomposed using the aerosol-assisted chemical vapour deposition technique at different temperatures to grow PbS nanostructures on glass substrates. These nanostructures were analyzed by XRD, SEM, TEM and EDX methods. Impedance spectroscopic measurements were performed for PbS in the frequency range of 40 to 6 MHz at room temperature. In a complex impedance plane plot, two relaxation processes were exhibited due to grains and grain boundaries contribution. A high value of dielectric constant was observed at low frequencies, which was explained on the basis of Koops phenomenological model and Maxwell–Wagner type polarization. Frequency-dependent AC conductivity results were compliant with Jonscher power law, while capacitance–voltage loop had a butterfly shape. These impedance spectroscopic results have corroborated the ferroelectric nature of the resultant PbS nanodeposition.
