Mn⁴⁺-doped fluoride phosphors are attractive for application in white solid-state lighting devices because their distinct red emission can improve the color rendering index, while the earth-abundance of Mn⁴⁺ ions can reduce the production cost. However, highly hazardous HF is used as the fluoride source in the synthesis processes, which requires extreme caution. In this review, we introduce various methods for synthesizing Mn⁴⁺-doped fluoride phosphors, categorized according to the presence or absence of HF in the synthesis. The underlying optical properties of the phosphors fabricated using the various methods are discussed. In addition, in the discussion of each method, we emphasize on the key factors and strategies for developing phosphors. Finally, this review highlights perspectives on and future directions for the safe synthesis of Mn⁴⁺-doped fluoride phosphors to achieve solid-state lighting devices with superior optical properties.

Mn ⁴⁺掺杂的氟化物荧光粉在白色固态照明设备中具有吸引力，因为它们独特的红色发光可以改善显色指数，而Mn ⁴⁺离子的富泥土可以降低生产成本。但是，在合成过程中，高度危险的HF被用作氟化物源，需要格外小心。在这篇综述中，我们介绍了多种合成Mn ^4+的方法掺杂的氟化物磷光体，根据合成中是否存在HF进行分类。讨论了使用各种方法制造的荧光粉的基本光学性能。此外，在每种方法的讨论中，我们重点介绍了开发荧光粉的关键因素和策略。最后，本综述重点介绍了安全合成Mn ⁴⁺掺杂的氟化物磷光体以实现具有优异光学性能的固态照明设备的观点和未来方向。
