配合物纳米晶体N-PbTMA的合成及其荧光性能研究

Synthesis and Photoluminescence Property of N-PbTMA Complex Nanocrystals

利用简单的微乳液法将醋酸铅和3-噻吩丙二酸配位,成功合成了一例含铅的配合物纳米晶体(记作N-PbTMA),并利用粉末X-射线衍射仪和场发射扫描电镜对其结构和形貌进行了表征。利用荧光分光光度计对N-PbTMA进行了荧光性能测试,当激发光波长为250 nm时,该配合物纳米晶体的荧光发射光谱在340 nm附近出现较宽的发射峰。

A lead complex nanocrystal(noted as N-PbTMA)was successfully synthesized by the coordination of lead acetate and 3-thiophene malonic acid through a simple microemulsion method.Its morphology and structure were analyzed and characterized by field emission scanning electron microscopy and X-ray diffractometer.The photoluminescence property of N-PbTMA was measured by fluorescence spectrophotometer.When the excitation wavelength was 250 nm,the fluorescence emission spectrum of N-PbTMA nanocrystals showed a wide emission peak near 340 nm.
