A series of Y-Al oxide:rare earth/TiO2 composites synthesized and characterized.
Yb:Er and Y-Al oxide (YAG): TiO2 ratios altered.
10% YAG with 2% Er and 15% Yb/TiO2 yielded a 50% enhancement than TiO2 in simulated sunlight.
Enhancements primarily attributed to increased dye adsorption and proximity between phases.
