Аннотация: <jats:title>Abstract</jats:title><jats:p>Far-red (FR) region (beyond 700 nm) lighting sources possess special potential for plant lighting. However, it remains a challenge to obtain high-performance Cr<jats:sup>3+</jats:sup>-doped FR phosphors. This study developed a FR phosphor, Ca<jats:sub>1.8</jats:sub>Mg<jats:sub>1.2</jats:sub>Показать полностьюAl<jats:sub>2</jats:sub>Ge<jats:sub>3</jats:sub>O<jats:sub>12</jats:sub>:Cr<jats:sup>3+</jats:sup> (CMAGG: Cr<jats:sup>3+</jats:sup>), using the cation substitution strategy. Under 438 nm blue light excitation, the phosphors display FR emission centered at 720 nm with a full width at half maximum (FWHM) of 91 nm. Benefit from the favorable match with the FR phytochrome (P<jats:sub>fr</jats:sub>), the phosphor is combined with InGaN blue light chips to create a FR phosphor-converted light-emitting diode (pc-LED), which is used in Italian lettuce growth experiments and it results shown in a 15% increase in fresh weight and a 6.5% increase in dry weight. Notably, supplemental FR light modulated its growth morphology. The results of this study will be useful for further research on novel Cr<jats:sup>3+</jats:sup>-doped FR phosphors to meet the precise spectral requirements for plant growth.</jats:p>
