摘要

提出了一种计算金属氧化物核壳纳米粒子有效介电函数的新方法，并与现有理论进行了比较。该方法可用于光催化或太阳能收集中广泛应用的核壳胶体和纳米复合材料的反射光谱、透射光谱和吸光度的预测。

Modelling metal-dielectric core-shell nanoparticles with effective medium theories

A new method for calculating the effective dielectric function of a metal-oxide core-shell nanoparticle is presented and compared with existing theories. This new approach can be helpful for predicting the reflectance, transmittance and absorbance spectra of core-shell colloids and nanocomposites which are widely used in photocatalysis or solar energy harvesting.
