我们从理论上开发了一类基于胶体晶体的非线性光学材料，这种材料是由悬浮在基质流体中的梯度金属介电纳米颗粒制成的。由于纳米颗粒内部的渐变以及周期性结构产生的晶格效应，这种材料可以具有光学非线性的增强和红移。
We theoretically exploit a class of colloidal-crystal-based nonlinear optical materials, which are made of graded metallodielectric nanoparticles suspended in a host fluid. Such materials can have both an enhancement and a redshift of optical nonlinearity, due to the gradation inside the nanoparticles as well as the lattice effects arising from the periodic structure.
