摘要
本文合成了表面修饰的Mn2O3，超微粒子（UFP）有机溶胶，并采用简并的四波混频（DFWM）手段研究了Mn2O3有机溶胶的三阶非线性光学特性，得到了较大的非线性极化率X3．最后讨论了Mn2O3超微粒子的三阶非线性产生机制．
In this paper Mn2O3 ultrafine particles (OFP) coated with DBS are synthesized. A study optical process is carried out with Degenerate Four Wave Mixing (DFWM) techniQue. The high third order optical nonlinear susceptibility X(3)of Mn2O3UFP sols is reported. The nonlinear mechanism is discussed.
