摘要：

We investigated the photo-structuring of silver-oxide films by using femtosecond laser pulses. The silver-oxide films were prepared by magnetron sputtering. The physical properties of the prepared silver-oxide films were investigated by using absorption spectroscopy. For the sample that underwent the photo-structuring of the silver-oxide films by two interfering femtosecond laser pulses, scanning and transmission electron microscopy measurements showed that a metal grating was formed through the photoreduction of silver oxide. Micro-photoluminescence spectroscopy showed spationally selective photoluminescence from the laser-modified region. In order to find the nature of laser-modified region, we compared the metal grating formed by laser interference structuring with the thermally annealed film.
