摘要
采用超声化学法在合成纤蛇纹石纳米管内进行了组装ZnS量子点的研究。利用X射线衍射仪(XRD)、透射电镜(TEM)及紫外-可见光谱仪对组装样品进行了表征。TEM观察发现在纤蛇纹石纳米管中组装了ZnS;XRD分析表明组装的ZnS量子点为β-ZnS结构,其平均晶粒度为4.2nm;紫外-可见吸收光谱研究表明ZnS量子点的吸收边红移5nm。
ZnS quantum-dots were assembled in synthetic chrysotile nano-tubes based on the ultrasonic chemical method, and the attributes of the assembled samples were studied by such means as powder X-ray diffraction （XRD）, transmission electron microscpy （TEM） and ultraviolet-visible spectroscopy （UV-Vis）. Transmission electron microscope （TEM） observation shows that ZnS quantum-dots were assembled in the nano-tubes of synthetic ehrysotile. XRD has revealed that the ZnS quantum-dots in the nano-tubes are β-ZnS and their average crystal granularity is 4.2 nm. The optical absorption side of the ZnS quantum-dots is shifted to the longer wavelength where the red shift is 5 nm.
