Synthesis of Silver Nano-Particles for the Application to Transparent Conductive Electrodes

Abstract

In this study, the solution plasma sputtering method was used in the synthesis of silver nanoparticles, instead of the chemical and physical synthesis method. Synthesis of the silver nanoparticles was conducted for 1 hour in 360 ml distilled water, and the effects of changing the input DC voltage and input frequency of the synthesized silver nanoparticles using power supply and the solution plasma sputtering method were analyzed via FESEM (field emission scanning electron microscopy) and EDS (energy-dispersive X-ray spectroscopy). The 8 kV input DC voltage in the solution plasma reactor was changed to 10 kV, and the 20 kHz input frequency was changed to 30 kHz, with the advanced device, which can control the input DC voltage and input frequency. It was confirmed that the average size of the silver nanoparticles became larger when the input DC voltage and frequency were changed.
