摘　　要：探讨了Fe_2O_3纳米团簇的合成条件.结果表明,各种合成条件对纳米团簇的形貌及大小有较大的影响.对该团簇的电学性质研究发现,它具有良好的顺磁特性,并对特定的光学区域具有敏感性,同时也对某种特定的电学状态具有较好的量子特性.This paper has studied the synthesis conditions of the Fe2O3 nanoparticles. Itis showed that the shape and size are varied greatly as the conditions of experimantal, Itis found that the nanoparticles have fine superparamagnatic and photosensitive proper-ties in the 300 and 580 nm area. And it is also found that the L-B film quantum struc-tures have fine memory function, in sorne applied voltage.
