Abstract
In this study, phosphor ceramics were fabricated, and optical properties were analyzed for application to nextgeneration automotive laser headlamps by using a spherical YAG : Ce phosphor with a garnet structure synthesized based on the spray drying method. The thickness of phosphor ceramic using spherical YAG : Ce phosphor was obtained with 100 ㎛, 150 ㎛, and 200 ㎛ to investigate the effect of thickness on optical properties such as light conversion efficiency, heat dissipation, luminance and color temperature. The results of this study are expected to play a significant role in the manufacturing process for the fabrication of phosphor ceramic by solving issues such as the high cost and low yield in the conventional liquid method to manufacture YAG : Ce nano fluorescent materials.
