Synthesis and properties of Zn1-xMnxS diluted magnetic semiconductors by hydrothermal method

  • 摘要: 以乙二胺为修饰剂,采用水热法合成了不同掺杂比例的Zn1-xMnxS(x =0,0.02,0.05,0.07)稀磁半导体材料,并通过XRD、FESEM、HRTEM、XEDS、光致发光光谱(PL) 和振动样品磁强计(VSM)对样品的晶体结构、形貌、光学性能和磁学性能进行表征。实验结果表明:本方法制备的所有样品具有结晶良好的纤锌矿结构,没有杂峰出现;样品形貌为一维的纳米棒状,分散性良好;掺杂的Mn2+以替代Zn2+的形式进入到ZnS晶格中,随着Mn掺杂量的增加晶格常数呈现收缩趋势;样品的PL光谱存在明显的紫外发光峰、蓝光发光峰和绿光发光峰,而且峰位发生蓝移;同时一定量的Mn掺杂ZnS纳米晶在室温条件下具有铁磁性。
    Abstract: Diluted magnetic semiconductors Zn1-xMnxS with different consistency ratios (x =0, 0.02, 0.05, 0.07) have been synthesized by hydrothermal method using ethylenediamine as a modifier. The crystal microstructure, morphology and optical and magnetic properties of the samples were characterized by XRD, FESEM, HRTEM and XEDS, photoluminescence spectra (PL) and the vibrating sample magnetometer (VSM). The experiment results show that all samples synthesized by this method possess wurtzite structure with good crystallization, and no other impurity phase appears. The morphology of the samples is one-dimensional nanorods and well dispersed. Mn2+ enters into the ZnS lattice to substitute for the lattice site of Zn2+, and the lattice constant decreases with the increase of Mn content. The PL spectra of the samples have obvious ultraviolet emission peak, blue emission peak and green emission peak, and the luminescence peak has a blue-shift. At the same time, a certain amount of Mn doped ZnS nanocrystals have ferromagnetic properties at room temperature.
