ABSTRACT Rare‐earth ion‐doped garnets with excellent luminescent properties show great potential for temperature sensing, displays, and nondestructive detection. However, their limited modes low photoluminescence quantum yields (PLQY) restrict further applications. In this study, we synthesized Al 3+ , Er ‐co‐doped Gd 3 Ga 5 O 12 multimode luminescence via a high‐temperature solid‐state method. Notably, the preferential substitution of ion at octahedral‐coordinated I sites significantly enhanced charge density electron transition probability, achieving PLQY enhancement down‐shifting from 35.1% to 68.5%. also influences relaxation during up‐conversion luminescence, resulting in color shift red yellow green. Additionally, incorporation increased photoelectric conversion efficiency light‐emitting diodes 2.9% 6.3% improved sensing sensitivity 2.7% 5.1% K⁻¹. This work provides new insights into photophysical mechanisms underscores key role optimizing optical garnet‐based materials.
