Abstract: A thin platinum film which is both conductive and transparent is produced by laser chemical vapor deposition of a suitable organometallic compound, such as allyl cyclopentadienyl platinum. After deposition, the film is annealed to increase the relative abundance of platinum with respect to carbon. The film can be further conditioned by electrically cycling the same in a bath of sulfuric acid.
