Morphology studies on craters created by femtosecond laser irradiation in UDMA polymer targets embedded with plasmonic gold nanorods
Abstract The effect of embedded plasmonic gold nanoparticles on the crater morphology was studied in 160 µm-thick UDMA–TEGDMA copolymer films irradiated by femtosecond single pulses of a Ti:Sa laser. The plasmonic absorption of the embedded gold nanorods had a resonance at the wavelength of the laser. It was observed that by increasing the laser intensity the diameter of the craters decreased, while the depth of the craters increased. In addition, the crater depths were significantly higher in the presence of gold nanorods. A threshold intensity of 1.5·10 17 W/cm 2 has been determined, above which a doubled roughness and sevenfold increased crater volume was observed in the polymer containing gold nanorods.
