解决了具有多个光谱特征的纳米粒子的复杂介电函数的恢复问题。结果表明，可以通过最大熵模型和表面等离子体共振光谱来获得水基质中纳米颗粒的复杂介电函数。本分析提供了识别纳米颗粒并获得其浓度信息的方法，这是监测液相纳米颗粒的重要因素。
The problem of the retrieval of the complex dielectric function of nanoparticles having multiple spectral features is addressed. It is shown that the complex dielectric function of nanoparticles that are in a water matrix can be obtained with a maximum entropy model along with surface-plasmon resonance spectroscopy. The present analysis provides means to identify nanoparticles and to gain information on their concentration, which are important factors in the monitoring of nanoparticles in liquid phase.
