Pulsed laser treatment of gold and black gold thin films fabricated by thermal evaporation

Original language description

he effect of pulsed laser treatment of metal, and metal blacks, was studied. Gold and black gold thin films were fabricated by thermal evaporation of gold in a vacuum and nitrogen atmosphere respectively. UV pulsed laser radiation (?=266 nm, ?=4 ns), with fluence ranging from 1 mJcm2 to 250 mJcm2was used for the film treatment in a vacuum and nitrogen atmosphere of pressure up to 100 kPa. Surface structure modifications were analyzed by optical microscopy, atomic force microscopy and scanning electron microscopy. Energy dispersive X-ray spectroscopy was used for chemical characterization of the samples. A significant dependence of the film optical and structural properties on laser treatment conditions (laser fluence, ambient pressure and number of applied pulses) was found. The fluence threshold for observable damage and initiation of changes of morphology for gold (106 mJcm2) and black gold (3.5 mJcm2) surfaces was determined.
