Abstract
We obtained ZnO Nanowires films deposited on two types of substrate (Si (100) and glass) with 12 wt % PbS as dopant by simple thermal evaporation technique. High Resolution Transmission Electron Microscopy (HRTEM) and Energy-dispersive X-ray spectroscopy(EDX) images have confirmed the formation of ZnO Nanowires (NWs). EDX technique was used to investigate the elements content (standard analysis and mapping modes). Morphology and thickness of the films were investigated from surface and cross section of the films via Scanning Electron Microscopy (SEM) images. The Raman, photoluminescence (PL) and X-ray Diffraction (XRD) have confirmed the hexagonal phase structure of the ZnO Nanowires, which appeared to be very fine and their diameters were less than 40 nm and their lengths were of several micrometers using SEM and HRTEM. The effect of PbS as dopant on the growth of ZnO Nanowires as well as on the morphology for two substrates was investigated and compared. These Nanowires films could be applied in several fields. Mapping -EDX has confirmed the stoichiometry of prepared films. Finally, the structure (phase) was verified by different characterization techniques. The optoelectronic application of Nanostructures film will be study later.
期刊介绍:
Orbital: The Electronic Journal of Chemistry is a quarterly scientific journal published by the Institute of Chemistry of the Universidade Federal de Mato Grosso do Sul, Brazil. Original contributions (in English) are welcome, which focus on all areas of Chemistry and their interfaces with Pharmacy, Biology, and Physics. Neither authors nor readers have to pay fees. The journal has an editorial team of scientists drawn from regions throughout Brazil and world, ensuring high standards for the texts published. The following categories are available for contributions: 1. Full papers 2. Reviews 3. Papers on Education 4. History of Chemistry 5. Short communications 6. Technical notes 7. Letters to the Editor The Orbital journal also publishes a number of special issues in addition to the regular ones. The central objectives of Orbital are threefold: (i) to provide the general scientific community (at regional, Brazilian, and worldwide levels) with a formal channel for the communication and dissemination of the Chemistry-related literature output by publishing original papers based on solid research and by reporting contributions which further knowledge in the field; (ii) to provide the community with open, free access to the full content of the journal, and (iii) to constitute a valuable channel for the dissemination of Chemistry-related investigations.
