Abstract

In this study, the properties of Ag-coated $TiO_2$ nanoparticles were observed, while varying the molar ratio of water and $Ag^+$ for the surfactant and $TiO_2$. According to the XRD results, each nanoparticle showed a distinctive diffraction pattern. The intensity of the respective peaks and the sizes of the nanoparticles increased in the order of AT1($R_1=5$)(33.3 nm), AT2($R_1=10$)(38.1 nm), AT3($R_1=20$)(45.7 nm), AT4($R_1=40$)(48.6 nm) as well as AT5($R_2=0.2$, $R_3=0.5$)(41.4 nm), AT6($R_2=0.3$, $R_3=1$)(45.1 nm), AT7($R_2=0.5$, $R_3=1.5$)(49.3 nm), AT8($R_2=0.7$, $R_3=2$)(57.2 nm), which values were consistent with the results of the UV-Vis. spectrum. The surface resistance of the conductive pastes fabricated using the prepared Ag-coated $TiO_2$ nanoparticles exhibited a range 7.0~9.0($274{\sim}328{\mu}{\Omega}/cm^2$) times that of pure silver paste(ATP)($52{\mu}{\Omega}/cm^2$).
