Abstract

ZnS nanowires films on Si (100) substrate have been obtained, using PbS as dopant, via thermal evaporation technique. High resolution transmission electron microscopy (HRTEM) images have confirmed the formation of ZnS nanowires. Energy dispersive X-ray analysis (EDX) has been employed to investigate the element’s contents (mapping and area analysis) and it has confirmed that the ZnS films were stoichiometry. Thickness and morphology of the films were explored from cross section of the films and surface, respectively, using scanning electron microscopy (SEM) and atomic force microscopy (AFM) images. These images confirmed the creation of ZnS nanostructures morphology. The diameter of the obtained nanowires is about 50 nm and their length is several micrometer. Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), and Photoluminance (PL) have confirmed the hexagonal phase with nanowires structure. UV-Vis characterization has been used to obtain the transparency and the band gap of ZnS films deposited on glass substrate. Also, these verified characterizations allowed to potential optical application in optoelectronic field

热蒸发法制备ZnS纳米线薄膜的HRTEM研究

以PbS为掺杂剂，采用热蒸发技术在Si（100）衬底上制备了ZnS纳米线薄膜。高分辨率透射电子显微镜（HRTEM）图像已经证实了ZnS纳米线的形成。能量色散X射线分析（EDX）已被用于研究元素的含量（映射和面积分析），并已证实ZnS膜是化学计量的。利用扫描电子显微镜（SEM）和原子力显微镜（AFM）图像，分别从薄膜的横截面和表面观察了薄膜的厚度和形貌。这些图像证实了ZnS纳米结构形态的产生。所获得的纳米线的直径约为50nm，并且它们的长度为几微米。傅立叶变换红外光谱（FTIR）、X射线衍射（XRD）和光亮度（PL）证实了具有纳米线结构的六方相。用紫外-可见光谱表征了玻璃衬底上沉积的ZnS薄膜的透明度和带隙。此外，这些经过验证的特性使其在光电子领域具有潜在的光学应用前景
