We report on the fabrication of a YAG: Ce3+/Al2O3 ceramic converter (YAGC) under various conditions for use in laser diode (LD)-based automotive lighting applications. The prepared YAGC shows improved luminous characteristics regarding the use of a pore forming agent and a change in the fabrication method. In particular, when the fabrication method of the YAGC changes, an area with a yellow ring is reduced to 37.4% compared to previous fabrication methods. The results of the study indicate that the change in the YAGC fabrication method can result in an alternative for high-quality YAGC fabrication for automotive lighting applications.
