Partial ion exchange in nanoparticles is a convenient method to prepare semiconductor alloy quantum dots and heterostructures, where both size and composition can be used to tune electronic properties. Complete exchange is also a useful method to grow some structures from more readily synthesized nanoparticle templates. The optical properties of CdxHg(1−x)Te alloy particles are studied.
