Bulk Polycrystalline Ceria Doped Al${}_2$O${}_3$ and YAG Ceramics for High-Power Density Laser-Driven Solid-State White Lighting: Effects of Crystallinity and Extreme Temperatures

E. H. Penilla, P. Sellappan, M. A. Duarte +3

Here we develop and characterize high thermal conductivity/high thermal shock resistant bulk Ce doped Al2O3 and propose it as a new phosphor converting capping layer for high-power…
