Transparent 1% Gd‐doped YAG and YAG ceramics were synthesized via solid‐state reaction spark plasma sintering using commercially available powder and TESO as a sintering additive. The highest in‐line transmission values achieved were 77.1% at 550 nm and 80.6% at 800 nm in the 1% (at.%) Gd‐doped YAG transparent ceramic with 99.90% relative density. Ultraviolet emission at 312.5 nm was observed in 1% Gd‐doped YAG ceramic via photoluminescence excitation, making it a promising material for applications in solid‐state UV devices.
