“…The crystal plane (2 0 0) is the prominently seen in the XRD pattern. This is in agreement with the report of [8]. The prominent peak in the XRD pattern corresponds to the galena, (PbS) mineral in the galena ore sample as other mineralogical content of the ore could be sphalerite (ZnS), Pyrite (FeS2), Chalcopyrite (CuFeS2), etc.…”

Dye is one of the principal parts for high power conversion efficiency in a Dye-Sensitized Solar Cell. Conspicuous developments have taken place via the work of several researchers in the engineering of novel dye structures so as to enhance the performance of the system. The properties of a natural mineral dye were studied in this work. The structure of the dye was determined and discovered to have contains constituents that could enhance better absorption of solar radiation for use in a Dye-Sensitized Solar Cell (DSSC). The Lead sulphide and iron content of the mineral dye studied as revealed by the X-Ray diffraction analysis done suggest this. The X-Ray Fluorescence (XRF) done revealed that the concentration of Lead and Iron (Fe) is high as compared to other elements present in the material, probably as a result of the fact that it is a geological sample (of the earth) and which may even suggest its colour and hence makes it absorbs solar radiation of visible region at its wavelength (around 380 nm – 800 nm). The functional groups present in the dye as obtained from the Fourier transform infrared spectroscopy are the Amine, Carbonyl, and hydroxyl groups, all of which confirm the suitability of the dye material in photosensitizing a semiconductor in a DSSC. The absorption spectra of the dye within the visible region of electromagnetic radiation show that the material has high, increased, and stable absorption of visible light which is suggesting a more durable natural dye for a DSSC than the easily degraded natural dyes of plants source.

“…δ values for all the PbS films were larger than zero, suggesting that the crystal faces were under transverse tensile stress parallel to the interface. Nanoparticle strain was mainly induced by edge dislocations [31]. Changes in film stress with C Pb and C S affected the absorption of PbS films in the near-infrared region.…”

Nanostructured copper particles are synthesized by Garcinia mangostana leaf extract as reducing agent with copper nitrate. X-ray diffraction study confirms the formation of nanocrystalline cubic phase of copper nanoparticles. The micro-structural properties such as grain size, strain, dislocation density and particle size are examined. The lattice constant is calculated using Nelson-Riley function. Physical parameters like lattice constants, stress, strain, dislocation density and size are calculated. Differential thermal analysis (DTA) and thermo gravimetric (TGA) have confirmed that nanoparticles have phase purity and weight loss percentage is 3.328%. The particle size calculated from XRD is 26.51 nm which is in good agreement with the results of W-H plot, SSP methods and particle analyser. The morphology of prepared copper nanoparticles is characterized by scanning electron microscope (SEM) and TEM. These biologically synthesized nanoparticles are highly antibacterial against Escherichia coli and Staphylococcus aureus. ª 2015 Production and hosting by Elsevier B.V. on behalf of King Saud University.
