Semiconducting Cd-Se nanoparticles have become an active area of research in recent years due to, among other reasons, their size-dependent light emission properties. These nanoparticles can be grown in laboratories and fine-tuned to exhibit desired optical and energy-absorbing properties. This Demonstration shows how these nucleation conditions can be altered by varying the parameters of temperature and composition in crystalline media. The nucleation rate is given by the equation:
