Development of high-power, high-efficiency blue light-emitting diodes (LED) based on III-V nitride semiconductor heterostructures has led to the era of solid-state lighting and technology convergence between photonics and various fields such as information and communication, agriculture, biology, and medicine. In this article, recent achievements and progress in the field of the III-nitride material system and its optoelectronic applications especially for high-power, high-efficiency short-wavelength LEDs are presented and reviewed. Major technical issues yet to be solved are also discussed as a means to recognize future technological trends and research activities.
