介绍了一种掺Nd₂O₃纳米颗粒的溶胶体系，对其光散射特性和消光系数进行了理论分析和数值模拟。结果表明，当溶胶体系中Nd原子的浓度为1.386×10^-20 cm^-3、Nd₂O₃纳米颗粒的半径为5 nm、相对折射率小于1.25时，对1064 nm波长激光的散射损耗不超过0.002 cm^-1。因此，掺Nd₂O₃纳米颗粒的溶胶体系可能是一种理想的激光介质。

A kind of colloid mixed with Nd₂O₃nano-particles is introduced. The light scattering characteristics and the extinction coefficient are analyzed and simulated. When the Nd atom concentration is 1.386×10^-20 cm^-3, the radius of Nd₂O₃ nano-particles is about 5 nm and the relative refractive index is less than 1.25, the results show that the scattering loss of the laser colloid at 1064 nm wavelength is less than 0.002 cm-1. Therefore, the laser colloid with Nd₂O₃ nano-particles may be is a kind of excellent laser medium.
