摘　　要：Lead iodide nanorods with a length of 500—3200 nm and a diameter of 35—130 nm were synthesized 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 ω0(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.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 as-prepared nanorods belong to hexagonal system.
