| Research Abstract |
There has been great interest in ink-jet printing on silica glass using nanoparticles for printable electronics. The novel transparent and electrical conductivity glass we prepared would be conducive to its use in optical sensor, light guide, optical lens, microchip etc. We demonstrated fabrication of electrically conductive pattern on silica glass using mesoporous silica and metal oxide nanoparticles. The pore size distribution of mesoporous silica was determined in terms of the poly(vinyl alcohol) amount as binder and the pH value in the suspension. The nanoparticles such as Ga2O3 doped ZnO(gallium-doped zinc oxide ) and In2O3-SnO2 (ITO, Indium tin oxide) could be printed on the surface or inside of the silica mesoporous and could form circuit pattern by co-sintering at 1200 degree. The ITO printed on silica glass has electrical conductivity after the sintering.
