Abstract Development of efficient sunlight conversion materials is critical for advancing sustainable agricultural practices, but current solutions often face challenges such as poor stability, high cost, and reliance on rare‐earth elements. This study presents a rare‐earth‐free xCsMnCl 3 (H 2 O) /(1−x)Cs SbCl 6 heterojunction ( x = 1−0.65) synthesized via an eco‐friendly mechanochemical method. By strategically combining Cs UV‐absorbing donor with CsMnCl red emitter. The optimized achieves remarkable 36‐fold enhancement at 626 nm (Full width half maxima (FWHM) 88 nm), perfectly matching chlorophyll a's absorption spectrum. Comprehensive experimental theoretical analyses, including UV–vis absorption, photoluminescence (PL) spectroscopy, density functional theory (DFT) calculations, reveal dual mechanism: i) interfacial electron‐hole transfer ii) suppression non‐radiative recombination through defect passivation. practical application demonstrated film fabricated by embedding the 0.75CsMnCl /0.25Cs composite in Ecoflex‐0030, which exhibits exceptional environmental stability (90% PL retention after 90 days) mechanical durability (500% tensile strain). plant growth experiments confirm film's efficacy, chives green cabbage rates increasing 1.5‐ 1.3‐fold, respectively, compared to natural light conditions. work not only addresses limitations existing light‐conversion also establishes rare‐earth‐free, platform energy‐efficient agriculture.
