Fe掺杂ZnS纳米线的制备及性能研究

利用水热法制备了Fe掺杂ZnS的纳米线．通过X射线衍射（XRD）、X射线能谱仪（EDS）、扫描电显微镜（SEM）和透射电子显微镜（TEM）分析了Fe掺杂对样品的结构和形貌的影响；利用紫外可见近红外分光光度计（uV-VIS）、共聚焦显微拉曼一荧光光谱仪（PL）和振动样品磁强计（VSM）对样品的光学特性进行表征．结果表明，样品为六角纤锌矿结构，Fe成功掺入ZnS晶格中，形成替位式掺杂．随着Fe掺杂浓度的增加，样品的吸收峰出现蓝移且发光强度逐渐减弱．掺杂后的样品在室温下呈现了铁磁性．

Synthesis and Properties of Fe Doped ZnS Nanowires

Abstraet：Fe doped ZnS nanowires were prepared by hydrothermal method. The effect of the Fe content on the structure and morphology of samples were investigated by X-ray diffraction （XRD）, X-ray energy dispersive spectroscopy （ EDS）, scanning electric microscope （SEM） and transmission electron microscope （ TEM ）, and the optical properties were studied by neams of ultraviolet visible near infrared spectrophotometer （ UV-VIS）, confocal microscopic Raman-fluorescence spectrometer （PL） and vibrating sample magnetometer （VSM）. The results show that the Fe doped ZnS nanowires possess hexagonal wurtzite structure, and Fe atom is as a substitute atom. With increasing the Fe content, the samples exhibit that the absorption peaks appear blue-shift and the luminous intensity changes weakness. The Fe doped ZnS samples show ferromagnetic property at room temperature. Key words： hydrothermal method ; Fe doped ZnS nanomaterials ; Nanowires ; ferromag netism ; optical properties
