Abstract
We have developed phosphor-free InGaN/GaN/AlGaN dot-in-a-wire core-shell white light emitting diodes, which can break the carrier injection efficiency bottleneck of conventional nanowire white light emitting diodes, leading to a dramatic enhancement of the output power. Additionally, such phosphor-free nanowire white light emitting diodes can deliver a very high color rendering index (CRI) of ~92-98.
