摘要：The uniform and monodisperse bismuth nanospheres were successfully prepared by simple and convenient solvothermal method. The bismuth nitrate was reduced by ethylene glycol at 150-200 degrees C for 20-30 hrs. The nanospheres were characterized by powder X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The dispersivity of bismuth nanospheres was investigated using optical microscope. The optimum reaction conditions to prepare the uniform bismuth nanospheres with a narrow diameter range was investigated. The results indicate that the monodisperse bismuth nanospheres prepared at 200 degrees C possess sizes ranging from 100-200 nm. The formation mechanism of the bismuth nanospheres was hypothesized.
