Metallic gold was deposited on several different substrates by laser pyrolysis of a goldcontaining ink. The gold was deposited in the form of lines by translating the substrate during laser pyrolysis; linewidths ranged from 10 Am to 1.5 mm. This process was performed in open air. Prior to annealing, the films contain 40 to 50 % carbon impurity and the resistivity is extremely high. After a 1 hour anneal in air, the carbon content is reduced to < 5 %, and the resistivity is reduced to roughly 13 times bulk gold. Further improvement may be possible with a different annealing schedule.
