摘要
为了提高蓝色薄膜电致发光器件 (TFEL)的发光亮度 ,自行配制了氟化铥 (TmF3) ,并制备了以ZnS :TmF3为发光层的薄膜电致发光器件 ,研究了TmF3的掺杂浓度对ZnS :TmF3发光器件发光特性的影响 .实验结果显示 ,当掺杂浓度为 1.2 %mol时 。
In order to increase the electroluminescent brightness of blue thin film electrolumincent device, the ZnS doped with TmF 3 are prepared from solid state reaction and the thin film electroluminescence devices with ZnS:TmF 3 active layer are prepared by electron_beam_evaporation method in our lab. We have investigated the influence of TmF 3 concentration on the electroluminescent characteristics of ZnS:TmF 3 TFEL device. With increasing TmF 3 concentration the relative intensity of the ZnS:TmF 3 increases and reaches maximum. The optimum concentration is at about 1.2% mol.
