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.

通过使用组合RF-MAGNERTRON溅射沉积法优化组合物，新开发了多颜色的双彩和稀土共掺杂（LA_2O_3）共掺杂（LA_2O_3）的氧化氧化物磷薄膜。 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.
