Abstract

After the successful commercialization for InGaN/GaN blue light-emitting diodes that are used to generate white light, the development of AlGaN based deep ultraviolet light-emitting diodes (DUV LEDs) promises the complete replacement for mercury-based fluorescence light tubes and this guarantees that the Minamata Convention on Mercury can be fulfilled by the end of the year of 2020. Therefore, developing high-efficiency AlGaN based DUV LEDs is regarded as the next revolutionary event for solid-state lighting. In this book, we will review the current status and summarize the challenges for DUV LEDs. Meanwhile, we also suggest the research spots that are worth investigating for DUV LEDs.
