KCl can act as a temperature conduction medium, and thus the raw materials can be uniformly heated. KCl can also act as a matrix to separate adjacent oparticles and avoid their aggregation ( Fig. 5c ), causing CDs1 to have a uniform band gap, which can reduce the channels of non-radiation transition, and achieve high solid-state fluorescence.

Substrates from these III-V materials also exhibit semiconducting properties in a manner similar to the column IV semiconductors such as silicon and germanium (Williams, 1990). Numerous semiconductor materials are based on III-Vpounds, most notably gallium arsenide (GaAs) and, more recently, gallium nitride (GaN).
