ScholarBank@NUS Repository. https://doi.org/10.1364/OE.20.014556||Abstract:||We present on a systematic study of the contribution of surface plasmon (SP) coupling and light extraction toward emission enhancement of Platinum (Pt) nano-patterns capped MgZnO films. Time resolved Photoluminescence (PL) results indicate that the Pt coating can greatly reduces the non-radiative recombination rate by passivation of surface states, making the decay slow down. Temperature dependence of the integrated photoluminescence intensity reveals that the Pt nano-patterns can offer a large amount of light transfer and scattering, which enormously increase the light extraction efficiency up to 3.8-fold. These results indicate that the increased light extraction efficiency caused by surface modification via Pt coating rather than SP coupling plays a dominant role in increasing bandgap emission of MgZnO film. © 2012 Optical Society of America.||Source Title:||Optics Express||URI:||http://scholarbank.nus.edu.sg/handle/10635/64866||ISSN:||10944087||DOI:||10.1364/OE.20.014556|
