| Summary, etc | Nanocrystalline thin films of Lead doped ZnS (ZnPbS) have been successfully<br/>synthesized by a simple and cost-effective technique named as Chemical Bath Deposition<br/>(CBD). Concentration of lead was varied from 3, 6, 9 and 12 %. The synthesis<br/>methodology has been optimized to achieve dense and smooth thin films on the surface<br/>of the glass substrates. The apparatus of Chemical Bath Deposition has been established<br/>locally using circulating water bath. After synthesis, structural, morphological and<br/>optical properties of deposited thin films have been studied to speculate the applications<br/>of these thin films. X-ray diffraction patterns reveals that the lead doped ZnS thin films<br/>exabit polycrystalline in nature. Broad diffraction peaks confirm the growth of material<br/>at nano level. A slight shift of diffraction peaks towards higher 2θ values is an evidence<br/>of lead incorporation into the ZnS lattice. The crystallite size varies from 4.86 to 5.99 Å<br/>as the concentration of lead increases from 3 to 12%. SEM micrographs show that almost<br/>spherical nanoparticles with an average size of 80 to 170 nm are uniformly distributed<br/>throughout the substrates surface. Growth of agglomerated particles having almost equal<br/>size represents the controlled growth of nanocrystals. Photoluminescence spectrum of<br/>ZnPbS thin films shows two peaks at 587 and 712 nm exabit that would be useful for<br/>advanced optoelectronic devices.<br/>Keywords: Chemical bath deposition (CBD), Pb doped ZnS thin films(ZnPbS), X-ray<br/>diffraction, Morphology, Photoluminescence. |
