【摘要】 采用化学方法使有机金属前驱体[In(5η-C5H5)]在不同条件下分解制备金属铟纳米颗粒和纳米线。前驱体在甲苯或四氢呋喃溶剂中分解时,配位体的种类与相对量、溶剂中的水含量和紫外线照射对分解产物的成分、形貌和尺寸有很大的影响。利用十六烷基胺(HDA)或氧化三辛基膦(TOPO)配位体的作用,前驱体均可分解得到铟纳米颗粒;而在HDA相对含量高、溶剂中不含水和在紫外线照射作用下,前驱体分解反应产物为铟纳米线。更多还原

【Abstract】 Indium nanomaterials were synthesized by chemical route.The decomposition of the organometallic precursor [In（η⁵-C₅H₅）] under different conditions leads to the formation of indium nanoparticles and indium nanowires.As the precursor is decomposed in toluene or tetrahydrofuran（THF）,the kinds and concentrations of ligands,the water content in the solvents and the UV irradiation have obvious influences on the composition,morphology and the dimension of decomposition products.The results show that,using trioctylphosphane oxide（（TOPO）） or hexadecylamine（HDA） as ligand,all of precursor [In（η⁵-C₅H₅）] decomposite and form the indium（nanoparticles）.When the HDA concentration is high,and there is no water,the decomposition of the precursor in dry solvent is the indium nanowires under UV irradiation.更多还原
