AlGaN Deep Ultraviolet Light-Emitting Diodes with Localized Surface Plasmon Resonance of Al Nanoparticles by using Block Copolymer Template |
| 초록 |
Research on localized surface plasmon resonance (LSPR) has recently attracted academia attention because of metal nano-structure having a size of nm can interact with electromagnetic waves and bring significant electromagnetic enhancement. In particular, Al nano structures below sereral tens of nanometer exhibit properties at deep ultraviolet regions. However, it is difficult to form metal nano structures below several tens of nanometers. In this study, we present a remarkable enhancement in AlGaN light-emitting diodes through the coupling of LSPR mediated by a high density array of Al nanoparticles (NPs). An array of Al NPs with the optimum resonance diameter of ~ 40 nm for 285-nm DUV emission had been achieved by using block copolymer self-assembly. The internal quantum efficiency was increased by 57.7% owing to the reduced radiative recombination lifetime mediated by LSP. |
