Surface Plasmon enhanced GaN based light-emitting diodes by Ag/SiO2 nanoparticles

摘要：

　　The QW-SP coupled nanorod LED with Ag/SiO2 nanoparticals (Nps) was fabricated.From both the light emission and the transmission spectrum,the energy coupling effects have been verified.The PL intensity of SP coupled LED increased by 2.1 times compared with the reference sample,combined with a blue shift of 2 nm from 456 to 454 nm.Furthermore,the time resolved photoluminescence (TRPL) results also confirm that the QW-SP coupling can enhance the carrier spontaneous emission rate dramatically.Our finding gives an alternative solution to fabricate QW-SP coupled LEDs to realize both high-power and high-speed.
