A thin platinum film is formed on a substrate of glass, alumina or pottery by applying on the surface of the substrate a solution containing one part by weight of an organic platinum complex represented by formula (I): PT (R1-C 3BOND C-R2)2 (I) wherein R1 and R2 each represents a group of phenyl, 4-methylphenyl or 4-methoxyphenyl and 0.1 to 100 parts by weight of an organic solvent dissolving the complex, then heating the coated film at the decomposition temperature of the complex and thereafter firing the film and 400 DEG to 900 DEG C. |
