Using the solution precursor plasma spray process Eu: Y2O3 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 Y2O3. 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 5D0 [RIGHTWARDS ARROW] 7F2 electric-dipole transition.
