Synthesis and photoluminescence properties of Nd2O3nanoparticles modified by sodium bis(2-ethylhexyl) sulfosuccinate

This paper reports that Nd 2 O 3 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 Nd 2 O 3 nanoparticles take the shape of sphere with 18 nm and 31 nm with different preparation. The organic sol of Nd 2 O 3 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 D 3/2 → 4 I 9/2 and 2 P 3 /2 → 4 I 11/2 or 4 D 3/2 → 4 I 13/2 were observed.
