Abstract: A fluoride phosphor includes fluoride particles represented by AxMFy:Mnz4+ where A is at least one selected from lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs), M is at least one selected from silicon (Si), titanium (Ti), zirconium (Zr), hafnium (Hf), germanium (Ge) and tin (Sn), a compositional ratio x of A satisfies 2≤x≤3, and a compositional ratio y of F satisfies 4≤y≤7; and an organic material physically adsorbed onto surfaces of the fluoride particles to allow the fluoride particles to have hydrophobicity. The fluoride particles have a concentration of Mn4+ gradually reduced from respective centers to respective surfaces of the fluoride particles.
