Metallic nanoparticles with optical properties produced

TEHRAN, Jan. 02 (MNA) – Iranian researchers have applied an economical method to produce metal oxide nanoparticles with specific optical properties for use in laser and information technology, INIC reports.

According to Iran Nanotechnology Initiative Council (INIC), the nanoparticles produced in this research have applications in materials sciences, laser and information technology. The method used in this research can be considered as a new way for the production of nanoparticles that increases efficiency and production rate in comparison with the usual methods.

The synthesis and design of metal nanoparticles and their oxides has significantly grown in recent years due to the growth in their application in various sciences. Various methods have so far been used for the production of metal and metal oxide nanomaterials, including radio methods, thermal degradation, chemical degradation and so on. The majority of methods are time-consuming and expensive; therefore, the aim of the research was to obtain a high-efficient and quick method to synthesize metal oxide nanoparticles. Sonoelectrochemical method has been used to obtain this goal.

Sonoelectrochemical method is one of the simplest and most economical methods in the production of nanoparticles. This method is a combination of ultrasonic waves with the convenient electrochemical method. In this method, smaller particles at nanometric dimensions are produced in comparison with the electrochemical method. The application of ultrasonic waves significantly increases the reaction rate during the process.

As a result, the new method has higher rate and efficiency in the synthesis of products in comparison with other methods. Due to their unique optical properties, the nanoparticles produced in this method can be used in the production of laser, information technology, fluorescence sensors, transistors, and biological degradation.

Results of the research have been published in Ultrasonics Sonochemistry, vol. 22, 2015, pp. 382-390.
