Japanese Researchers Develop Silicon QD-based White-blue LED

A Si quantum dot (QD)-based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence has been fabricated by Professor Ken-ichi SAITOW (Natural Science Center for Basic Research and Development, Hiroshima University), Graduate student Yunzi XIN (Graduate School of Science, Hiroshima University), and their collaborators. A hybrid LED is expected to be a next-generation illumination device for producing flexible lighting and display, and this is achieved for the Si QD-based white-blue LED. For details, refer to "White-blue electroluminescence from a Si quantum dot hybrid light-emitting diode," in Applied Physics Letters; DOI: 10.1063/1.4921415.
