97 percent light absorption in an ultrabroadband frequency range utilizing an ultrathin metal layer: randomly oriented, densely packed dielectric nanowires as an excellent light trapping scaffold
(Royal Society of Chemistry, 2017)In this paper, we propose a facile and large scale compatible design to obtain perfect ultrabroadband light absorption using metal-dielectric core-shell nanowires. The design consists of atomic layer deposited (ALD) Pt ... -
Ag@SiO2-embedded InGaN/GaN nanorod array white light-emitting diode with perovskite nanocrystal films
(Elsevier, 2021-10-28)White light-emitting diodes (LEDs) are great candidates for general lighting. Phosphors have commonly been used for the color conversion layers of white LEDs; however, they backscatter more than half of the down-converted ... -
Correction to: Active tuning from narrowband to broadband absorbers using a sub-wavelength VO2 embedded layer
(Springer, 2021-02-04)Metamaterial perfect absorbers (MPAs) with dynamic thermal tuning features are able to control the absorption performance of the resonances, providing diverse applications spanning from optical switches and filters to ... -
Electroluminescence efficiency enhancement in quantum dot light-emitting diodes by embedding a silver nanoisland layer
(Wiley-VCH Verlag, 2015)A colloidal quantum dot light-emitting diode (QLED) is reported with substantially enhanced electroluminescence by embedding a thin layer of Ag nanoislands into hole transport layer. The maximum external quantum efficiency ... -
Plasmonic metamaterial based structures for designing of multiband and thermally tunable light absorbers, multiple thermal infrared emitter, and high-contrast asymmetric transmission optical diode
(Bilkent University, 2021-07)Metamaterials with sub-wavelength nanostructures refer to a class of synthetic materials that possess exotic electromagnetic properties which cannot be observed with natural materials. Negative refractive index, asymmetric ... -
Sensitivity comparison of localized plasmon resonance structures and prism coupler
(2014)Plasmon resonances are widely used in biomolecular sensing and continue to be an active research field due to the rich variety of surface and measurement configurations, some of which exhibit down to single molecule level ... -
Strong coupling between localized and propagating plasmon polaritons
(OSA - The Optical Society, 2015)We investigate plasmon-plasmon (PP) coupling in the strongly interacting regimes by using a tunable plasmonic platform consisting of triangular Ag nanoprisms placed nanometers away from Ag thin films. The nanoprisms are ...
