This project is focusing on the shape of silver nanoparticles and the aspect ratio of silver nanowires for the control of their absorption spectrum in the visible light to infrared ranges. Synthesis of metal nanoparticles has become increasingly important in science and engineering. Being able to control the processes is vital to success in applications and uncovering the mechanisms of nanoparticle production. Nanowires are one of the varieties of nanoparticles that will be utilized for this project. There are many different metals that can be used to synthesize nanowires, I am focusing on silver. Silver exhibits the highest thermal conductivity out of all metals (Sun, 2001). Silver nanowires with a large aspect ratio also show an absorbance of higher wavelengths then other nanoparticles, like spherical silver nanoparticles (Sun, 2001). Other silver particles that exhibit similar characteristics and show a higher wavelength absorbance will be considered as well. Controlling reaction conditions allow plasmonic, oscillatory quantum motion, colloids to obtain architecturally predictable nanostructures and can be used to understand their optical properties (Motl, 2013). There are many shapes that nanoparticles can take up. Each shape, on the nanoscale shows different properties that can be utilized, such as conductivity, anisotropy, and, what I am interested in, absorbance of light.
I have used the work that Jana et al. conducted regarding a batch process synthesis of silver nanowires as a basis for generation of our silver nanowires. I will use a solution based process that is cost effective, quick, and easy to control for the uniform synthesis of silver nanowires and other silver nanoparticles. Microreactor-assisted nanomaterial de...
