SEM micrograph of (a) periodic, (b) Fibonacci array Au nanocylinders with , and . (c) AFM of Fibonacci nanoparticle array. (d) The experimental setup for PL measurements.
Normalized transmission spectra of periodic and Fibonacci Au nanoparticle arrays with specified interparticle separations .
(a) Integrated PL enhancement in periodic (circle) and Fibonacci (square) nanoparticle arrays of various interparticle separations. The inset shows the representative PL spectrum of periodic (bottom), Fibonacci (top) nanoparticle arrays with and unpatterned area (middle). (b) PL lifetime of periodic (circle), Fibonacci (square), unpatterned (triangle). Inset Er decay of unpatterned (star) and Fibonacci arrays with different as specified in the legend.
