Abstract
AgNO3-polyethylene glycol aqueous solution was deposited by inkjet printing on a soda-lime silicate glass substrate as a dot-array, in which the size of the dots was about 100 micrometer. Then, the glass substrate was heat-treated at 300 oC for 12 hours. The substrate was transparent and colorless after the heat-treatment. However, a yellow-colored dot-array appeared after a second heat-treatment at 550 oC for 30 minutes. This shows that the silver ions were selectively incorporated into the glass substrate where the solution was applied resulting in the formation of periodical compositional modification in the surface of the glass substrate.
