In_2O_3 nanorods were prepared by sol-gel technique with nonionic surfactant controlling their morphology,and were characterized by TEM,TG-DSC and XRD.The results indicated that In_2O_3 nanorods had the length of about 120 nm and diameter of 20 nm.The In_2O(OH)_4 dried gelatin was formed by partial dehydrating of In(OH)_3 molecules.The factors influencing the morphology of In_2O_3 nanorods and their growth mechanism were discussed.The geometry array parameter P of the nonionic surfactant was between 1/3～1/2 through calculation,which confirmed that the shape of the micelle was claviform.

These factors influencing the morphology of In_2O_3 nanorods and their growth mechanism were discussed. The geometry array parameter P of the nonionic surfactant was between 1/3 and 1/1. 2 through calculation, which confirmed that the shape of the micelle was claviform.
