Synergetic Contributions of High Quenching Concentration and Tuned Square Antiprism Geometry Boosting Far-Red Emission of Eu³⁺ with Near-Unit Efficiency.

ABSTRACT: Far-red phosphors have emerged as a desirable research hotspot owing to their critical role in promoting plant growth. Especially, Eu³⁺ ions typically present the ⁵D₀→⁷F_J (J = 0, 1, 2, 3, 4) transitions, which overlap with the far-red light required for plant photosynthesis. However, achieving high-efficiency far-red emission of Eu³⁺ remains challenging due to weak ⁵D₀→⁷F₄ transition and concentration quenching. The study constructs two anomalously efficient far-red garnet phosphors A₃Sc₂C₃O₁₂ (A = Y³⁺, Gd³⁺. C = Al³⁺, Ga³⁺):Eu³⁺. A high-resolution STEM measurement equipped with an ab
