MAGNETIC Gd2O3 NANO-PARTICLES SYNTHESIS AND CHARACTERIZATION
Following the route from the atomic scale where quantum mechanics is applied to the macroscopic scale where classical physics or chemistry rules, we go through a “nanoworld”; an area where we can find new and enhanced material properties such as magnetic permeability not found in either the atomic or macro scale. A technique named reverse micelle used in this research allows for the synthesis of very small magnetic gadolinium oxide crystals. The size of crystals obtained with this method varies from 10 to 250 nm in diameter. One goal of the project was to develop a synthesis procedure to give a satisfying yield as well as good cleanliness of obtained crystals. Once met, the next goal was to characterize the particles using different techniques: x-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), dynamic light scattering (DLS) and photoluminescence (PL). The information from these techniques will help draw a connection between synthesis procedure and final material properties. As a result his project will help to expand the knowledge and understanding of nano-scale material structure and properties.
