Solution Precursor Plasma Spray Eu: Y₂O₃ Phosphor Coating

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.

Application of solution precursor spray techniques to obtain ceramic films and coatings

“…The performance of an entire SOFC with electrolyte produced by SPS and cathode by APS was tested in temperatures from 650 to 800°C, and some parameters of the cell are shown in Figure 5.9. Finally, the optical properties of Eu:Y 2 O 3 coatings obtained by SPPS were tested by Chen et al (2012). The same research group compared the performance of SOFC with YSZ electrolyte made using the technologies of SPPS and of SPS (Marr et al, 2014).…”

A Simple Solvothermal Synthesis of Spherical Y₂O₃:Eu³⁺

“…Europium-doped yttrium oxide (Y 2 O 3 :Eu 3+ ) nanophosphors have been successfully used in high-resolution and projection television systems owing to their exceptional advantages, such as good color coordinates, short decay time, high quantum efficiency, and excellent material stability [1,2]. The Y 2 O 3 :Eu 3+ nanophosphors have emerged as a potential alternative to the conventional red-emitting Y 2 O 2 S:Eu phosphors, as the substrate material Y 2 O 3 is considered to be highly stable, non-toxic and harmless [3].…”
