“…The corresponding optical photos given in the insets show different reflected colors, which are ascribed to the different diameters of PS colloid spheres array. For the same type of silver nanostructrual arrays, the uniform diffraction color indicates that the high-ordered PS colloid spheres array is formed . The formation of these silver nanostructrual arrays are strongly dependent on the etching time of PS colloid spheres array in the silver nanobowls.…”

“…Based on the geometric calculation of the close-packed PS colloid spheres array, 11 For the same type of silver nanostructrual arrays, the uniform diffraction color indicates that the high-ordered PS colloid spheres array is formed. 26 The formation of these silver nanostructrual arrays are strongly dependent on the etching time of PS colloid spheres array in the silver nanobowls. When the etching time is 0 s, only the nanocaps array is observed.…”

“…Fischione Instruments Inc.). With the increase of etching time, the diameter of the PS colloid sphere decreased gradually while the shape and periodicity of the PS colloid spheres array kept unchanged . Finally, the silver film of 20 nm was deposited on the etched PS colloid spheres array in the silver nanobowls using the same depositing conditions.…”

An easy-handling and low-cost method is utilized to controllably fabricate nanopattern arrays as the surface-enhanced Raman scattering (SERS) active substrates with high density of SERS-active areas (hot spots). A hybrid silver array of nanocaps and nanotriangles are prepared by combining magnetron sputtering and plasma etching. By adjusting the etching time of polystyrene (PS) colloid spheres array in silver nanobowls, the morphology of the arrays can be easily manipulated to control the formation and distribution of hot spots. The experimental results show that the hybrid nanostructural arrays have large enhancement factor, which is estimated to be seven times larger than that in the array of nanocaps and three times larger than that in the array of nanorings and nanoparticles. According to the results of finite-difference time-domain simulation, the excellent SERS performance of this array is ascribed to the high density of hot spots and enhanced electromagnetic field.
