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.
Key words: indium; nanoparticle; nanowire; organometallic precursor; ligand
