Nano structure of a lead (II) coordination polymer [Pb(CClO)(NO)(CHN)] (1), has been synthesized by a sonochemical method in different concentrations. The nano particles were characterized by scanning electron microscopy (SEM) X-ray powder diffraction (XRD), FT-IR spectroscopy and elemental analyses. The thermal stability of nano structure is closely investigated via thermal gravimetric (TGA), and compared with crystalline structure. The compounds are then heated to 600 °C to produce PbO nano particles. The resulting PbO is characterized through XRD and SEM analyses. Concentration of initial reagents effects on size and morphology of nano-structured compound 1 have been studied and show that low concentrations of initial reagents decreased particles size and leaded to uniform nano particles morphology. The photoluminescence properties of the prepared compound, as crystalline and as nanoparticles, have been investigated. The result showed a good correlation between the size and emission wavelength.
通过超声化学方法在不同浓度下合成了铅（II）配位聚合物[Pb(CClO)(NO)(CHN)]（1）的纳米结构。通过扫描电子显微镜（SEM）、X射线粉末衍射（XRD）、傅里叶变换红外光谱（FT-IR）和元素分析对纳米颗粒进行了表征。通过热重分析（TGA）对纳米结构的热稳定性进行了深入研究，并与晶体结构进行了比较。然后将化合物加热至600℃以制备PbO纳米颗粒。通过XRD和SEM分析对所得的PbO进行了表征。研究了初始试剂浓度对纳米结构化合物1的尺寸和形态的影响，结果表明低浓度的初始试剂会减小颗粒尺寸并导致纳米颗粒形态均匀。对制备的化合物作为晶体和纳米颗粒的光致发光性质进行了研究。结果表明尺寸与发射波长之间具有良好的相关性。
