Abstract
A water solution of lead nitrate is infiltrated into a substrate made of a porous material, and liquid drops of a water solution of sodium sulfide, which is charged into a ink cartridge of a minute nozzle, are sprayed onto the substrate from the minute nozzle. The lead component from the lead nitrate water solution and the sulfur component from the sodium sulfide water solution are synthesized directly on the substrate, and thus, a thin film made of lead sulfide is formed on the substrate.
