论文摘要：Driven by the demand for high-performance red color converters in wide-color-gamut displays and high color-rendering-index lighting, Mn4+-activated fluoride phosphors stand out for their nontoxicity, efficient blue-light absorption, and narrow-band red emission. However, the fluoride crystalline lattice presents a critical trade-off: despite enabling excellent luminescent output, it intrinsically introduces two major limitations, namely, poor moisture stability and inadequate control over the particle size and morphological uniformity. Such drawbacks severely restrict the widespread commercial deployment of these phosphors in next-generation lighting and display devices. This Spotlight on Applications begins by systematically elaborating on the basic crystal architectures and photoluminescence behaviors of Mn4+-doped fluoride red phosphors. We subsequently center our discussion on the two core technical bottlenecks mentioned above and comprehensively overview cutting-edge progress from our research team and peer groups in three core research directions: surface and crystal reconstruction strategies, precise tuning of particle dimension and morphology, and environmentally benign synthetic methodologies. By analyzing typical experimental observations and deciphering the fundamental mechanisms governing material design and structural modification, this work delivers actionable design guidelines for fabricating fluoride red phosphors that integrate high luminous efficiency, robust environmental stability, tunable particle geometry, and excellent device compatibility. Moreover, this review is anticipated to accelerate the technical advancement and industrial translation of such narrow-band fluorides as state-of-the-art red-emitting functional materials for advanced optoelectronics.
