Silicon and other Group IV nanomaterials are heavy metal free, light-emitting materials that could be used in applications such as biomedical imaging, LEDs, solar cells, photodetectors, and sensors. They have potential to offer bandgaps ranging from visible to short wave infrared by tuning size and shape. Under certain conditions, they can have excellent light-emitting properties. This presentation will focus on our lab's recent work synthesizing quantum-sized Group IV nanomaterials, characterizing their optical properties. I will discuss the synthesis of Si and Ge quantum dots and nanosheets, and the dependence of their properties on their size, shape, and surface chemistry. I also discuss their potential for solid-state lighting, photodetection, and biological sensing applications.
