 Abstract

- Aqueous gold nanoparticle dispersion was synthesized by chemical reduction method using diethanolamine as reducing agent and polyethyleneimine as dispersion stabilizer. The synthesis conditions for the stable dispersion of the gold nanoparticle suspension were determined by changing the amount of the reducing agent and dispersant during the wet chemical synthesis procedures. The face centered cubic lattice structure of the gold nanoparticles was confirmed by using X-ray diffraction and the morphologies of the nanoparticles were observed by transmission electron microscope. The synthesized gold nanoparticle dispersion was concentrated by evaporating the dispersion medium at room temperature followed by the addition of ethyleneglycol as humectant for the increase of the elastic properties to obtain gold nanoparticle inks for direct ink writing process. The line patterns were obtained with the gold nanoparticle inks during the writing procedures and the morphologies of the fine patterns were observed by scanning electron microscope.

Abstract

- Hexagonal barium ferrite (BaFe_12O_19) nano-particles have been successfully fabricated by spraypylorysis process. BaFe_12O_19 precursor solutions were synthesized by self-assembly method. Diethyleneamine (DEA) surfactant was used to fabricate the micelle structure of Ba-DEA complex under various DEA concentrations. BaFe_12O_19 powders were synthesized with addition of Fe ions to Ba-DEA complex and then fabricated BaFe_12O_19 powders by spray-pyrolysis process at the temperature range of 800sim1000°C. The molar ratio of Ba/DEA and heat-treatment temperatures significantly affected the magnetic properties and morphology of BaFe_12O_19 powders. BaFe_12O_19 powders synthesized with Ba/DEA molar ratio of 1 and heat-treated at 900°C showed the coercive forces (iHc) of 4.2 kOe with average crystal size of about 100 nm.
