Using the solution precursor plasma spray process Eu : Y 2 O 3 phosphor coating was deposited. The phase composition, microstructure, and photoluminescent properties of the as‐synthesized powders and as‐deposited coatings were investigated. XRD analysis indicated that the coating is composed of cubic Y 2 O 3 . SEM micrographs reveal the as‐sprayed coating is porous with a thickness of ~150 μm. Photoluminescent property measurement indicated that the phosphor coating exhibits the strongest emission at 612 nm, which is assigned to 5 D 0 → 7 F 2 electric‐dipole transition.
