| Research Abstract |
Multi-color-emitting Bi-and rare-earth co-doped(La_2O_3)-based multicomponent oxide phosphor thin films were newly developed by optimizing the composition using a combinatorial rf-magnetron sputtering deposition method. For example, high PL intensity and luminance in blue emission were obtained in postannealed((La_2O_3)_<0.9>-(Ga_2O_3)_<0.1>): Bi phosphor thin films and TFEL devices fabricated using postannealed((La_2O_3)_<0.85>-(Ga_2O_3)_<0.15>): Bi thin films, respectively.
