In article number 1900345, Xiangjiang Liu, Longhua Tang, and co‐workers demonstrate a method to generate a large area and uniform nanoflower array with well‐defined petal shape. The double‐layered nanospheres are innovatively used as a mask and an etched substrate, and controllable tailoring is achieved by adjusting the etching degree and sputtering thickness. The arrays show tunable optical and surface‐enhanced Raman scattering enhancement effects.
