摘要

利用水热法合成了未掺杂和mn掺杂的ZnS，并利用x射线衍射(XRD)、x射线能谱(EDX)、场发射扫描电镜(FE-SEM)、傅里叶变换红外光谱(FT-IR)和紫外可见光谱对其进行了表征。XRD谱图证实了纳米颗粒的立方闪锌矿晶体结构。由于Mn的掺杂，所有样品的晶粒尺寸都有所增加。FE-SEM图像显示合成样品呈球形形貌。EDX光谱证实了掺杂样品中Mn的存在。FTIR光谱显示掺杂改变了Zn-S吸收带的位置。随着掺杂率从0到10%的增加，吸收最大值出现红移，带隙减小。

To Study the Impact of Mn Doping on Structural, Morphological and Optical Properties of Zinc Sulfide

By utilising hydrothermal approach undoped and Mn-doped ZnS was synthesized and characterized by using X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), Field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR) and UV-Visible spectroscopy. The XRD pattern confirmed the cubic sphalerite crystal structure of prepared nanoparticles. Due to Mn doping, size of crystallite for all the samples was increased. FE-SEM images showed spherical morphology of synthesized samples. The EDX spectrum confirms the presence of Mn in the doped sample. FTIR spectrum showed that doping shifts the position of Zn-S absorption band. A red shift was observed in the absorption maxima and the bandgap was decreased with increasing doping percentage from 0 to 10%.
