铜纳米晶是通过混合反胶束中铜离子的化学还原得到的。大量过量的还原剂有利于产生新一代的成形铜纳米晶体，如纳米盘、细长纳米晶体和立方体。通过使用紫外可见光谱和数值光学模拟，我们证明了光学性质的调整的相对比例的球体和纳米盘。
Copper nanocrystals are obtained by chemical reduction of copper ions in mixed reverse micelles. A large excess of reducing agent favors producing a new generation of shaped copper nanocrystals as nanodisks, elongated nanocrystals, and cubes. By using UV-Visible spectroscopy and numerical optical simulations we demonstrate that the optical properties are tuned by the relative proportions of spheres and nanodisks.
