Аннотация: <jats:title>Abstract</jats:title><jats:p>Cr<jats:sup>3+</jats:sup>-doped phosphors are highly recognized in various fields for their remarkable luminous efficiency and spectral flexibility, including modern agriculture and horticulture. However, the shortage of suitable Cr<jats:sup>3+</jats:sup>-doped phosphors for far-red LED deviПоказать полностьюces has inhibited their popularization in plant lighting. Herein, an innovative Cr<jats:sup>3+</jats:sup>-doped phosphor Ca<jats:sub>2</jats:sub>YAl<jats:sub>3</jats:sub>Ge<jats:sub>2</jats:sub>O<jats:sub>12</jats:sub>:Cr<jats:sup>3+</jats:sup> (CYAG:Cr<jats:sup>3+</jats:sup>), achieving a broad far-red emission at 770 nm upon 450 nm blue light excitation is designed. The optimal CYAG:Cr<jats:sup>3+</jats:sup> phosphor exhibits a high internal quantum yield of 78.2% and low thermal-quenching behavior of 85%@373 K. Thus, the fabricated phosphor-converted LEDs (pc-LEDs) for plant far-red lighting have a high output power of 33.3 mW and photovoltaic conversion efficiency of 11.5% at 100 mA. The potential of CYAG:Cr<jats:sup>3+</jats:sup> in plant lighting is assessed by supplementing the far-red lighting of Italian lettuce with fabricated pc-LEDs, and the biomass of Italian lettuce is significantly increased by 33%. The successful development of CYAG:Cr<jats:sup>3+</jats:sup> phosphors provides a high-quality option for plant far-red light devices and further stimulates the development of new Cr<jats:sup>3+</jats:sup>-doped plant-lighting phosphors.</jats:p>
