Morphology and microstructure of crystalline YAG-Al2O3 composites grown by the horizontal directional crystallization

Thermally robust and highly stable bulk luminescent materials are essential for advancing high‐power laser‐driven lighting. In this study, we report a yellow–green LuAG:Ce–Al2O3 eutectic, synthesized using the laser‐heated pedestal growth (LHPG) technique. The emission intensity of the eutectics reaches a maximum at an Al2O3 content of 20% due to the enhanced light scattering. Additionally, owing to the high thermal conductivity of Al2O3, the prepared LuAG:Ce–Al2O3 eutectic exhibits low thermal quenching, with only a 5% loss in luminescence observed at 150°C, along with a high luminance saturation threshold of approximately 15.8 W·mm−2. When irradiated under blue laser excitation at 7.9 W, the prepared LuAG:Ce–Al2O3 eutectic demonstrates a luminous flux of 1917 lm and a luminous efficacy of 242.4 lm·W−1. These results highlight that the potential of LuAG:Ce–Al2O3 eutectics as luminescent materials for high‐power laser‐driven lighting applications.
