| 摘 要： | 本文利用桥式平衡电路及Sawyer-Towre电路系统地测量了薄膜电致发光(TFEL)器件的损耗电流波形,发光亮度波形及电荷电压回线.在实验基础上建立了TFEL电子传输过程的物理模型和等效电路,由克希霍夫定律可建立激活层的瞬态电压及电流的微分方程,由此导出损耗电流波形,发光亮度波形及Q-V回线的数学表达式.利用计算机模拟将计算结果与实验进行比较,利用四个调节参数即得到与实验相当好的拟合.

| Abstract: | The dissipative current waveform,brightness waveform and charge voltage characteristics of the TFEL device with MISIM structure have been measured by using a bridge circuit and Sawyer-Tower circuit,in which a sinusoidal voltage is used.It is observed that the positive half cycle waveform of the dissipative current and the negative one are asymmetry.The brightness waveform has the same property. |
