In this paper, we report our investigation effect of concentration of silver nanowires (AgNWs) solution on the AgNWs thin films coated onto a glass substrate by simple Meyer-rod coating. Diameter and length of AgNWs have used about 120 nm and 20 to 30 µm, respectively. Concentration of AgNWs were variated of 186 mg/ml, 210 mg/ml, and 223 mg/ml in ethanol solution. AgNWs thin films then were heated at temperature 90 °C for 20 min. The UV-vis spectrophotometry, scanning electron microscope (SEM), and four-point-probe were employed to characterize the AgNWs thin films. The result shows that concentration of AgNWs solution affects on the transmittance and a sheet resistance of the AgNWs thin films. The transmittance at the wavelength of 550 nm is obtained 94.5% by a sheet resistance about 1.2 Ω/sq. The higher concentration of AgNWs solution can decrease the sheet resistance and the transparency of the AgNWs thin films.
