Optical Refractive Index Sensors with Plasmonic and Photonic Structures: Promising and Inconvenient Truth
Yi Xu,Yi Xu,Ping Bai,Xiaodong Zhou,Yuriy Akimov,Ching Eng Png,Lay Kee Ang,Wolfgang Knoll,Lin Wu +8 more
TL;DR: In this paper, the authors focus on optical refractive index (RI) sensors with no fluorescent labeling required, and utilize two parameters to characterize and compare the performance of optical RI sensors: sensitivity to RI change (denoted by symbol SRI) and figure of merit (in short, FoM).
Journal ArticleDOI
Stabilization of 4H hexagonal phase in gold nanoribbons
Zhanxi Fan,Michel Bosman,Xiao Huang,Ding Huang,Yi Yu,Khuong P. Ong,Yuriy Akimov,Lin Wu,Bing Li,Jumiati Wu,Ying Huang,Qing Liu,Ching Eng Png,Chee Lip Gan,Peidong Yang,Hua Zhang +15 more
TL;DR: The high-yield solution synthesis of gold nanoribbons in the 4H hexagonal polytype, a previously unreported metastable phase of gold, is reported, which may open up new strategies for the crystal phase-controlled synthesis of advanced noble metal nanomaterials.
Journal ArticleDOI
Design of Plasmonic Nanoparticles for Efficient Subwavelength Light Trapping in Thin-Film Solar Cells
Yuriy Akimov,W. S. Koh +1 more
TL;DR: In this paper, the geometry-sensitive scattering from plasmonic nanoparticles deposited on top of a thin-film amorphous silicon solar cell was explored to enhance light trapping in the photoactive layer.
Journal ArticleDOI
Heterophase fcc-2H-fcc gold nanorods.
Zhanxi Fan,Michel Bosman,Zhiqi Huang,Ye Chen,Chongyi Ling,Chongyi Ling,Lin Wu,Yuriy Akimov,Robert Laskowski,Bo Chen,Peter Ercius,Jian Zhang,Xiaoying Qi,Min Hao Goh,Yiyao Ge,Zhicheng Zhang,Wenxin Niu,Jinlan Wang,Haimei Zheng,Hua Zhang +19 more
TL;DR: The wet-chemical synthesis of gold nanorods with a well-defined fcc-2H-fcc heterophase, which possess unique optical and catalytic properties is reported, which possesses superior electrocatalytic activity for the carbon dioxide reduction reaction under ambient conditions.
Journal ArticleDOI
Control of LED Emission with Functional Dielectric Metasurfaces
Egor Khaidarov,Egor Khaidarov,Zhengtong Liu,Ramón Paniagua-Domínguez,Son Tung Ha,Vytautas Valuckas,Xinan Liang,Yuriy Akimov,Ping Bai,Ching Eng Png,Hilmi Volkan Demir,Hilmi Volkan Demir,Arseniy I. Kuznetsov +12 more
TL;DR: In this paper, a novel concept for metasurface integration on LED is proposed, using a cavity to increase the LED spatial coherence through an angular collimation, which does not come at the price of any reduction in the total emitted power.
