摘　　要：Employing a silver nano semi-ellipsoid nanoarray with high symmetry into applications in plasmonic color printing,we fulfill printing images with colors independent of observing angles.Also,by decreasing the period of a nano semi-ellipsoid array into deep-subwavelength scales,we obtain high reflectivity over 50%,promising high efficiency for imaging generations.A facile technique based on the transfer of anodized aluminum oxide template is developed to fabricate the silver nano semi-ellipsoid nanoarray,realizing plasmonic color printing with features of low cost,scalable,full color and high flexibility.Our approach provides a feasible way to address the angledependent issue in the previous practice of plasmonic color printing,and boosts this field on its way to real-world commercial applications.
