In this study, quantum dots with Au/CdSe complex cores composed of Au as a metal base were synthesized, syrup was prepared, and coated on natural simulated LED unit modules, and the optical properties of traffic signs using them were investigated, and the following conclusions were obtained. The nanoparticles synthesized at 260°C and 280°C grew into irregular shapes with PL wavelengths of 624-627㎛, half-widths of 35㎛, PL-QY ratios of 55-61%, and grain diameters of 5-7㎛. The quantum dot syrup was applied to the LED unit module to produce a traffic sign composed of 4CL unit modules, and the luminance of 179 ㏅/㎡, insulation resistance of 10,000㏁, and insulation withstand of 500V were achieved, meeting the performance and specifications of the standard guidelines for luminescent traffic safety signs. The surface temperature of the unit module laminated with 4CL resin is 24~25℃, which shows a stable heat distribution, confirming that it can be applied as a sign using unit modules.
