Abstract

III-nitride nanowire light-emitting diodes (LEDs) have emerged as the nextgeneration solid-state lighting technology. Currently, white-light LEDs rely on the phosphor-converted white LED (pc-WLEDs) technology, which normally depends on the mixture of blue/ultraviolet emitters and green/yellow/red color-converters. In this chapter, a summary of current research progress on nanophosphors and their applications in improving the device performance of InGaN nanowire pc-WLEDs in terms of color rendering properties and optical and electrical characteristics is presented. These investigations have concentrated on manufacturing methods, morphologies, optoelectronic characterizations and device performances. By concentrating on these critical elements, our goal is to contribute valuable insights and advancements to the field, paving the way for the continued development and application of III-nitride nanowire LEDs in the landscape of solid-state lighting technologies.
