Selective Deposition of SiO2 on Ion Conductive Area of Soda-lime Glass Surface.

ABSTRACT: Selective deposition of SiO2 nanoparticles was demonstrated on a soda-lime glass surface with a periodic sodium deficient pattern formed using the electrical nanoimprint. Positively charged SiO2 particles generated using corona discharge in a cyclic siloxane vapor, were selectively deposited depending on the sodium pattern. For such phenomena to occur, the sodium ion migration to the cathode side was indispensable to the electrical charge compensation on the glass surface. Therefore, the deposition proceeded preferentially outside the alkali-deficient area. Periodic SiO2 structures with 424?nm and 180?nm heights were obtained using one-dimensional (6??m period) and two-dimensional (500?nm period) imprinted patterns.
