Journal ArticleDOI
Visible-Frequency Dielectric Metasurfaces for Multiwavelength Achromatic and Highly Dispersive Holograms
Bo Wang,Fengliang Dong,Qitong Li,Dong Yang,Chengwei Sun,Jianjun Chen,Jianjun Chen,Zhiwei Song,Xu Lihua,Weiguo Chu,Yun-Feng Xiao,Yun-Feng Xiao,Qihuang Gong,Qihuang Gong,Yan Li,Yan Li +15 more
TL;DR: In this article, visible-frequency silicon metasurfaces formed by three kinds of nanoblocks multiplexed in a subwavelength unit constitute a metamolecule, which are capable of wavefront manipulation for red, green, and blue light simultaneously.
Journal ArticleDOI
Large-scale synthesis of nitrogen-rich carbon nitride microfibers by using graphitic carbon nitride as precursor
Yuanchun Zhao,Zheng Liu,Weiguo Chu,Li Song,Zengxing Zhang,Dongli Yu,Yongjun Tian,Sishen Xie,Lianfeng Sun +8 more
TL;DR: One-dimensional structures of nitrogen-rich carbon nitride are synthesized via a thermal evaporation process as discussed by the authors, where the C-N atomic rings (s-triazine and/or tri-striazine) present in the precursor remain stable during the process and act as basic building blocks during microstructure assembly.
Journal ArticleDOI
Gold Nanorod-Seeded Growth of Silver Nanostructures: From Homogeneous Coating to Anisotropic Coating
Yanjuan Xiang,Xiaochun Wu,Dongfang Liu,Zhi-Yuan Li,Weiguo Chu,Lili Feng,Ke Zhang,Weiya Zhou,Sishen Xie +8 more
TL;DR: The interaction of CTAB and metal can be utilized to tune the shapes of bimetallic structures and resulted in an orange slice-like shape for the Au@Ag nanocrystal.
Journal ArticleDOI
Formation of Rectangularly Shaped Pd/Au Bimetallic Nanorods: Evidence for Competing Growth of the Pd Shell between the {110} and {100} Side Facets of Au Nanorods
Yanjuan Xiang,Xiaochun Wu,Dongfang Liu,Xingyu Jiang,Weiguo Chu,Zhi-Yuan Li,Yuan Ma,Weiya Zhou,Sishen Xie +8 more
TL;DR: The competing growth of a Pd shell on the {110} and {100} facets of Au nanorods (Au NRs) results in the disappearance of unstable facets and the formation of rectangularly shaped Pd/Au bimetallic nanorod that show only four stable side surfaces.
Journal ArticleDOI
Polarization Encoded Color Image Embedded in a Dielectric Metasurface.
Xiaofei Zang,Xiaofei Zang,Fengliang Dong,Fuyong Yue,Chunmei Zhang,Xu Lihua,Zhiwei Song,Ming Chen,Pai-Yen Chen,Gerald S. Buller,Yiming Zhu,Songlin Zhuang,Weiguo Chu,Shuang Zhang,Xianzhong Chen +14 more
TL;DR: A novel metasurface platform is demonstrated for simultaneously encoding color and intensity information into the wavelength-dependent polarization profile of a light beam, which may open a new avenue for novel, effective color display elements with fine control over both brightness and contrast.
