估计进导带的具体结构，计算了碰撞激发截面，从其六个主要特征中看出过热电子能量的重要性，提出了分层优化方案，对预热，加速、发光层分别优化以提高过热电子能量，并以谱线丰富的Ｅｒ３＋离子作为发光材料的激活剂，利用其发光强度的蓝或绿红比定性地表示电子的能量，从发光的亮度、效率、蓝红或绿红比都显示了这一方案的优越性．进一步分析了过热电子的能量分布、倍增发生的区域及其系数、场致发光强度与能级寿命的关系、发光的二次陡升、激发态的离化、能量弛豫及传递、界面上的能带断错及弯曲、深陷阱的空间分布等．它们的数据都支持分层优化方案的正确性、优越性 The structure of the conduction band was estimated. The collision excitation cross section was calculated and the importance of overheated electron energy was discerned from its six main features. A layered optimization scheme was proposed to optimize the preheating, accelerating and light emitting layers separately to increase overheating Electron energy, and the rich line of Er3 + ions as a light-emitting material activator, the use of its luminous intensity of the blue or green to red qualitatively represent the energy of the electron, from the luminous brightness, efficiency, blue-red or green-red ratio is displayed The superiority of this program. The energy distribution of overheated electrons, the region of multiplication and its coefficient, the relationship between the electroluminescence intensity and energy level lifetime, the second steep rise of luminescence, the dissociation of excited state, the energy relaxation and transfer, With the fault can be broken and curved, deep trap spatial distribution. Their data support the correctness and superiority of the hierarchical optimization scheme
