Achieving Thermally Stable YAl3–xGax(BO3)4:Cr3+ Near-Infrared Emitting Phosphors via Chemical Substitution for Plant Growth LEDs

Indoor plant cultivation has been receiving increased attention due to concerns about sustainable agricultural production. Phosphor-converted light-emitting diodes (pc-LEDs) offer substantial promise as lighting solutions for regulating plant growth. However, the quest for high-performance phosphors with precise responsiveness to far-red phytochromes poses a challenge. Our study proposes a chemical substitution strategy to develop near-infrared (NIR) phosphors, YAl
