    采用两步法成功制备聚苯胺包覆硫化锌（PANI＠ZnS）量子点复合纳米材料。首先，在150℃水热法条件下制得 ZnS量子点；然后，将苯胺单体分散在 ZnS 量子点溶液中，原位聚合形成 PANI＠ZnS 量子点复合纳米材料。所得的产物分别用X 射线衍射法（XRD）、透射电子显微镜（TEM）、紫外可见吸收光谱（UV －vis）、红外光谱仪（IR）、拉曼光谱仪（Raman）等进行了表征。产物的荧光测试显示：PANI＠ZnS 复合量子点的发光峰相对于 ZnS 量子点的发光峰变宽，且其发射光谱的频率有明显的蓝移。

    PANI@ZnS quantum dots composite materials were prepared by two steps.First,ZnS quantum dots were synthesized by hy-drothermal method at a constant temperature of 150℃,and then PANI@ZnS composite quantum dots were obtained with the in situ polymerization of aniline.The products were characterized by X -ray diffractometer (XRD),ultraviolet -visible spectra (UV -vis), infrared spectra (IR),Raman spectra (Raman),transmission electron microscopy (TEM).The PL patterns show that the PANI@ZnS peaks are broaden compared to the ZnS peak and exist the clearly blue shift.
