Unlocking dual Mn³⁺/Mn⁴⁺ emissions in garnet phosphors for WLED and plant growth lighting applications.

ABSTRACT: Garnet-based lattices (A₃B₅O₁₂) have emerged as promising hosts for Mn co-doping due to their wide band gap and robust mechanical properties. However, challenges in stabilizing Mn³⁺, balancing Mn³⁺/Mn⁴⁺ emissions, and optimizing synthesis for thermal stability and efficiency have limited practical applications. In this study, Gd₃Ga₅O₁₂ (GGG) garnet was synthesized with Mn³⁺ and Mn⁴⁺ co-doping via a simple solid-state reaction. The incorporation of Mn ions into octahedral [GaO₆] sites and optimizing the synthesis condition to enhance photoluminescence (PL) properties were investigated. The phosphor achieved 100% color purity, 0.32 eV activation energy, 2
