摘　　要：This paper reports that Nd2O3 nanoparticles modified by AOT（sodium bis（2-ethylhexyl） sulfosuccinate） were prepared using microemulsion method in the system of water and propanol/AOT/toluene. Transmission electron microscopy shows that the Nd2O3 nanoparticles take the shape of sphere with 18 nm and 31 nm with different preparation. The organic sol of Nd2O3 nanoparticles is very stable at room temperature. X-ray diffraction results show that the product has hexagonal phase structure. Two ultraviolet emission band at 344 nm and 361 nm corresponding to the transition of ^4 D3/2→4 I9/2 and 2P3/2→^4I 11/2 or ^4D 3/2→ ^4 I 13/2 were observed.This paper reports that Nd2O3 nanoparticles modified by AOT（sodium bis（2-ethylhexyl） sulfosuccinate） were prepared using microemulsion method in the system of water and propanol/AOT/toluene.
