電圧印加を併用した固体イオン交換法によるガラス中への多層構造の形成

抄録

Using electric-field-assisted solid-state ion exchange, metal ions were doped into borosilicate glass surface. When a silver foil was used as a dopant, a buried silver layer was formed in glass substrate by additional voltage application with opposite direction to the case of doping (referred to as reverse voltage). Because the formed layer was electrically conductive, we tried to create a buried silver electric circuit in glass substrate. Especially for the multi-layer formation, silver and sodium were alternatively doped to glass surface. As a result, the three-layered structure consisted of sodium- or silver-rich layers was successfully formed in a glass substrate. By the reverse voltage application, a silver precipitation layer connecting between silver-rich layers in double- and three-layered structures was formed.
