Metal oxide nanoparticles suspension for optoelectronic devices fabrication
Abstract
In the present work, simple and single step method has been used to prepare metal oxide Nanoparticles suspension, this done by laser ablation of pure metal in liquid, While direct spraying of the prepared of the prepared colloidal suspension on silicon substrate leading to the formation of heterojunction device. The x-ray diffraction results insure the formation of monocrystallines ZnO nanoparticles with a wirtize structure. The atomic force microscopic result also show a direct depended of the particle size on laser parameter such as laser fluency number of laser pulse and laser wavelength.
