Abstract

Metal nanoclusters, which exhibit extraordinary physical and chemical properties that are different from their bulk counterparts, are highly promising nanomaterials for photonics. Recently, the use of two-photon excitation to fabricate silver nanoclusters in polymers was reported but still lacks speed and flexibility which are imperative for applications such as labeling and spectroscopy. Here, we demonstrate the fabrication of fluorescent nanocluster microstructures using spatially phase-shaped laser beams. Using an incident power of 60 mW and exposure time of 8 s, we found that the smallest line-width of the fluorescent microstructures is 478 nm, which is comparable to the line-width achieved with a two-photon laser scanning approach. As a proof-of-principle demonstration, the technique is used to fabricate fluorescent micro-labels that could be used in anti-counterfeiting applications.

Experimental setup for parallel DLW of silver nanocluster microstructures. The components are laser source (LS), attenuator (A), lens (L1, L2, L3, L4, L5, and L6), mirrors (M1 and M2), half wave plate (HWP), spatial light modulator (SLM), iris (I), dichroic mirror (DM), exposure beam blocking filter (F), camera (C), objective (O), sample and stage (S) and light emitting diode (LED).

(a) Bright field and (b) corresponding fluorescence microscopy image of a micro-star written with parallel DLW. The fluorescence image was recorded using LED light of intensity of 2 MW/m2 and excitation wavelength of 470 nm. Line-width of micro-star was estimated by plotting the fluorescence intensity profile along the dashed red lines. (c) Measured line-widths of the written structures with different laser powers as a function of exposure time.
