Gadolinium aluminum gallium garnet doped with cerium (Gd 2.99 Al 2.00 Ga 3.00 O 12.00 :Ce 0.01 , or GAGG :Ce) powders has been synthesized with high‐energy ball milling ( HEBM ) and solution combustion synthesis ( SCS ) techniques. The structures and morphologies of the powders were characterized through use of powder X‐ray diffraction ( PXRD ), photoluminescence ( PL ) measurements, dynamic light scattering ( DLS ), scanning electron microscopy ( SEM ), transmission electron microscopy ( TEM ), and UV ‐decay time measurements. Changes in the mechanochemically produced powders were monitored over time, while the solution combustion synthesis of GAGG :Ce was conducted using various ratios and types of fuels. In both production methods, particle sizes on the order of microns gave evidence of agglomeration.
