自1991年Iijima^[1]发现碳纳米管以来,在新一代量子器件和纳米结构器件需求的驱动下,一维纳米材料的设计合成迅速成为材料科学领域中的热点和前沿^[2,3]。碘化铅是一种具有层状结构的半导体材料,层内具有较强的化学键,层与层间则为较弱的范德华力,它与高分子复合则可制备三阶非线性光学材料。另外,它还可以用于制作室温核辐射探测器和辐射成像器件等^[4]。
Lead iodide nanorods with a length of 500-3200 nm and a diameter of 35-130 nm were synthe- sized in an inverse microemulsion system consisting of water, Triton X-100, cyclohexane and n-hexanol. The prepared products were characterized via TEM and XRD. The results show that ωο( the molar ratio of water to surfactant), the concentration of reactants, reaction temperature and aging time all can affect the morphology and size of the lead iodide nanorods prepared. The as-prepared nanorods belong to hexagonal system.
