Abstract:

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 → 7F2 electric‐dipole transition.
