Abstract

We use scanning fluorescence microscopy and electron beam lithography to probe the mechanism of fluorescence enhancement by periodic arrays of silver nanostructures, determining the optimum size and spacing of both Ag nanowires and Ag nanocolumns for incident light of different wavelengths and polarizations. Finite difference time domain (FDTD) calculations show a systematic variation with spatial period and incident polarization of the local electric field above the surface of the arrays which correlate well with that of the measured fluorescence enhancement, but a lack of a simple proportionality indicates that the dependence of the radiative and nonradiative decay rates on array geometry must be included in models for this effect. The dependence of the enhancement on spatial period and polarization indicates the importance of surface plasmon standing waves in this effect.

Fig. 1. (a) Scanning electron microscope image with enlargements of select areas shown to the left (a1–a4). (b) Reflectance image with incident light of 514 nm. (c) Cy3 fluorescence map. (d–e) Quantitative analysis of fluorescence enhancement (blue) and reflectance intensity (red) along two different orientations of excitation. The period is defined as the line width plus edge-to-edge spacing, and in this case line width equals edge-to-edge spacing. Chosen line widths vary by 1/8 the wavelength of the excitation light, for both wavelengths used (514 nm for the top half, and 633 nm for the bottom half). Line widths in the top two rows are 64 nm, 128 nm, 192 nm, etc. up to 514 nm, and in the bottom rows are 79 nm, 158 nm, 237 nm, etc. up to 633 nm for the largest square. Each half consists of longitudinal and transverse orientations plus a single vertical line. The “LPS” marks consist of arrays of silver nanodots with edge lengths of 120 nm and center-to-center spacings of 220 nm. For transverse excitation polarization, there is an inverse correlation between reflectance measurements and fluorescence enhancement; when reflectance is lowest, fluorescence intensity is highest. Error bars represent the standard deviation for several measurements of different samples.

(b) Reflectance image with 514 nm incident light, and (c) the corresponding Cy3 fluorescence map. (d) Quantitative analysis of the fluorescence enhancement (blue) and reflectance intensity (red) for increasing nanoparticle size and spacing. Particle edge lengths and center-to-center distances are the same as the bar widths and spacings in figure 1. The “LPS” mark consists of arrays of 120 nm silver nanodots with a period of 220 nm. Error bars represent the standard deviation for several measurements of different samples.

Fig. 3. Field intensity calculation by two-dimensional FDTD method and examples are as shown in (a-e). The long axis of the nanobars is normal to the image plane; this is an end-on view of the long structures positioned on a silicon substrate, with a layer of aluminum oxide between the substrate and the silver bars, and water filling the top portion of the frame. Bright areas show the positions of high local electric field. (f, g) Summary plots show the average electric field intensity 8 nm above the surface (at the location of the green dashed lines in (a–e)), compared with fluorescence enhancement along two different polarizations. Excitation polarization compared to bar orientation is indicated by the illustrations within the graphs. Intensity plots (a–e) represent the visualization of calculations for points noted by the labels within graphs (f–g), at periods of 316, 1028, 316, 512, and 1028 nm, respectively. Error bars represent the standard deviation for several measurements of different samples.

Graphs show the summary analysis along the transverse mode between fluorescence and (c) reflectance, or (d) calculated average field intensity 8nm above sample surface. Error bars represent the standard deviation for several measurements of different samples. There is good correlation between fluorescence and field intensity, and an inverse correlation between fluorescence and reflectance, for this transverse excitation.
