| 摘要: 以氯化铅和硫氰酸钾为原料，乙二醇为溶剂，采用简捷溶剂热技术制备了半导体PbS纳米棒基树枝晶。粉体用XRD、XPS、FESEM、TEM和ED进行了表征。单个PbS树枝晶具有三维空间结构，由一个主干和四个相互垂直侧枝组成。主干长2～10 μm，直径150～300 μm，每组侧枝纳米棒相互平行，沿主干垂直生长，棒长0.1～1.5 μm，直径80～180 nm。并对生长过程进行了探讨。 |

| Abstract: Using PbCl2 and KSCN as raw materials, nanorod-based PbS dendritic crystals were prepared in ethylene glycol (EG) under facile and mild solvothermal conditions. The as-prepared product was characterized by XRD, XPS, FESEM, TEM and ED. The individual PbS dendrite has three-dimensional (3D) structure with one trunk and four branches in a cross-like shape. The length of the trunk is in the range of 2～10 μm, with diameter of 150～300 nm. The branches have the length of 0.1～1.5 μm and the diameter of 80～180 nm, which grow in parallel with each other along directions perpendicular to the trunk. The possible growth mechanism is also discussed. |
