摘要:	摘要： We report a phase-modulated multicolor meta-hologram (MCMH) that is polarization-dependent and capable of producing images in three primary colors. The MCMH structure is made of aluminum nanorods that are arranged in a two-dimensional array of pixels with surface plasmon resonances in red, green, and blue. The aluminum nanorod array is patterned on a 30 nm thick SiO2 spacer layer sputtered on top of a 130 nm thick aluminum mirror. With proper design of the structure, we obtain resonances of narrow bandwidths to allow for implementation of the multicolor scheme. Taking into account of the wavelength dependence of the diffraction angle, we can project images to specific locations with predetermined size and order. With tuning of aluminum nanorod size, we demonstrate that the image color can be continuously varied across the visible spectrum. 其他題名： Nano Lett 出版者： United States: American Chemical Society 出版日期： 2015-05-13 出處： Nano letters, 2015-05, Vol.15 (5), p.3122-3127 資源來源： ACS publications 版權： Copyright © American Chemical Society 識別號： ISSN: 1530-6984 識別號： EISSN: 1530-6992 識別號： DOI: 10.1021/acs.nanolett.5b00184 識別號： PMID: 25844757
