چکیده:

Nanosized metal clusters possess chemical and physical properties that are distinct from those of bulk phase or individual molecules and can be used in fields such as optics, optoelectronics and catalysts. In this work silver nanoparticles were deposited on silica submicrospheres with aid of ultrasound power. A mixture of silver nitrate and ammonia solution with silica submicrospheres are irradiated by ultrasound waves under an atmosphere of argon. The resulting silver –silica nanoparticles is characterized with X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis. The results show a suitable silver-silica nanocomposite.
