Iranian, Swiss Researches Discover Different Characteristics of Nanoantennas

Iran | Posted on February 7th, 2010

"The mentioned research aimed to investigate the effect of nanoparticle material upon quantum gain and emission rate in nanoantennas," Ahmad Mohammadi, researcher in chief, explained to the Iran Nanotechnology Initiative Council.

Nanoantennas in Nano-optics act as ordinary antennas used in telecommunications and Electronics. Their design entails investigation of different parameters on nanoantennas' optical properties and in most cases gold and silver nanoparticles were selected. Accordingly, finding materials having similar performances in expanded spectrum ranges is a very interesting issue in nanosystems.

Describing the method the influence of nanoparticle material on quantum gain and emission rate was investigated, Mohammadi said, "To calculate molecule emission power, classical emission model of dipole near nanostructures was applied. Such a work necessitates complex calculations in classical Electrodynamics and as there existed no analytical solutions to these structures, a numerical technique known as FDTD (Finite Difference Time Domain) was used."

He underlined that they have investigated gold, silver, copper and aluminum nanoparticles by calculating their quantum gains and emission rates from infrared to ultraviolet wavelength.

"The results indicate that gold and copper are suitable for infrared spectrum range applications while silver is proper for visible range and aluminum can be applied for ultraviolet spectrum range," the Iranian scientist added.

"Thanks to an appropriate design, this research has shown that other materials such as copper and aluminum can be used as replacements for synthesizing nanoantennas."
