D)it is very costly.

Question

Quizplus · Accepted Answer

Silicon is not a good emitter of light because it is an indirect bandgap material. This means that light emission from silicon involves an inefficient process of indirect band-to-band transitions, resulting in weak and inefficient light emission. Hence, it is not well-suited for applications such as optoelectronics or light emission devices.
