Description

Gold microstructures are produced with a femtosecond laser in thin films of a polystyrene sulfonate matrix containing gold ions. Two-photon induced metal reduction is obtained by addition of 0.1 wt % of ruthenium(II)tris(bipyridine) in the formulation. Laser power is reduced to 5 mW, thereby limiting thermal effects. Lines of typically 150 nm heights and 1 μm widths are fabricated as well as freestanding bidimensional structures. An additional electroless plating step produces gold structures with conductivities only ten times smaller than the bulk metal
