| Outline of Final Research Achievements |
To develop white-emitting inorganic thin-film electroluminescent (TFEL) devices using oxide phosphors, the photoluminescent (PL) and EL characteristics in new blue-emitting Bi- or Eu-activated multicomponent oxide thin-film phosphors, and the PL characteristics in the thin films and nanoparticles of yellow-emitting Y3Al5O12:Ce phosphors were investigated. Intense emissions in the ultraviolet-blue region were obtained in PL from some Bi- or Eu-activated oxide phosphors, such as Y3Ga5O12:Bi, Y4Ga2O9:Bi and (SrO)-(Al2O3):Eu, prepared using a combinatorial dip coating method followed by postannealing. In addition, intense yellow PL emission was observed from the Y3Al5O12:Ce phosphor thin films and nanoparticle phosphors prepared under optimized methods and conditions.
