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.

采用组合射频磁控溅射沉积方法优化成分，新开发出多色发射Bi和稀土共掺杂(La_2O_3)基多元氧化物荧光粉薄膜。例如，分别在后退火((La_2O_3)_<0.9>-(Ga_2O_3)_<0.1>)：Bi荧光粉薄膜和使用后退火((La_2O_3)_<0.85>-(Ga_2O_3)_<0.15>)：Bi薄膜制造的TFEL器件中获得了高PL强度和蓝色发射亮度。
