摘要
该文分别以草酸钠、丁二酸钠、己二酸钠为PbWO_(4)纳米晶生长阶段的结构导向剂,采用直接沉淀法制备了具有有序纳米结构的PbWO_(4),用X-射线粉末衍射(XRD)、扫描电子显微镜(SEM)和红外光谱(IR)等技术手段对产物的结构进行了表征,研究了不同种类的双羧基阴离子对制备的PbWO_(4)纳米晶产物荧光性质的影响.PbWO_(4)有序纳米结构的形成可能原因是:双羧阴离子与PbWO_(4)纳米晶的某些晶面络合,进而影响到PbWO_(4)纳米晶的生长.
In this report,PbWO_(4) with ordered nanostructures are synthesized by direct precipitation method,in which biscarboxyion compound such as sodium oxalate,sodium succinate and sodium adipate,is employed as structure-directing agent in the growth stage of PbWO_(4) nanocrystals.With the aid of X-ray power diffraction(XRD),scanning electron microscopy(SEM)and infra-red spectrum(IR),it is confirmed that the ordered nanostructure of PbWO_(4) may be due to the complexation of biscarboxyion with some surface of PbWO_(4) nanocrystalline,thus affecting the growth of PbWO_(4).On the basis,the fluorescence properties of as-synthesized products by different biscarboxyion compound are further investigated.
