Description
As technology advances, more efficient, cost-effective materials and processes are being developed to serve the duties of optical materials within networks. As light transfers data through polymer optical materials, the polymeric matrix absorbs the signal and this phenomenon is known as attenuation. Attenuation occurs via the higher vibrational energies with respect to fluoropolymers that are inherent with hydrocarbon amorphous polymers like polymethyl methacrylate (PMMA).
One solution to realize efficient light emission is to incorporate nanoparticles into the polymer matrix. In the research presented, aqueous solution-polymer precipitation was used to synthesize light harvesting ligand capped luminescent nanoparticles. Tb3+:LaF3 was the chromophore in surface treated inorganic nanoparticles which were used to produce color emitting polymer nanocomposites. Dynamic light scattering (DLS), Transmission Electron Microscopy and Scanning Transmission Electron Microscopy were utilized in order to characterize the size of the nanoparticle and agglomerates. Nanoparticle diameters were approximately 5 nm where the agglomerate diameters ranged from 37 ± 2 nm when synthesized in methanol and 388 ± 188 nm when synthesized in water.
Presenter Bio
Kyle Gipson, Assistant Professor, Engineering, James Madison University
Dr. Gipson joined the JMU School of Engineering in 2011. While at Clemson University, Dr. Gipson conducted research about polymer nanocomposites for optical applications in addition to engineering education research centered on increasing diversity within STEM disciplines.
Prior to pursuing his Ph.D., Dr. Gipson served in various positions with Milliken & Company. The last position he held with the company was Technical Manager for one of their business units. In this capacity, he managed the development and deployment of new-to-world products, product enhancements and product design modifications engineered to meet specific end-use applications.
