| 摘 要： | 本文利用有机发光材料4，4′，4″，-{N，-（2-naphthyl）-N-phenylamino}-triphenylamine（2T-NATA）作为空穴缓冲层，制备了结构为：ITO／2T-NATA／NPB／DPVBi／Alq3／LiF／Al的有机电致发光器件．在器件的制备过程中通过改变空穴缓冲层2T-NATA的厚度使器件的亮度和效率得到了改善．当2T-NATA的厚度为15nm时，器件的性能最好．在电流密度为623mA/cm^2时最大亮度达到16530cd／m^2，对应的电流效率为2．65cd／A，器件的色坐标为（0．23，0．36），属于蓝绿光发射．

| Abstract: | We have fabricated organic light-emitting devices with the structure of ITO/2 T-NATA/NPB/DPVBi/Alq3/LiF/Al by using the organic materials 2 T-NATA as the hole buffer layers.Both the luminance and efficiency of organic light-emitting devices have been improved by changing the buffer layers thickness.When the thickness of 2 T-NATA is 15 nm,the performance of devices is the best.The device shows the maximum luminance of 16530cd/m2 and the corresponding luminous efficiency of 2.65 cd/A at the current density of 623 mA/cm2. The CIE chromaticity coordinates of(0.23,0.36) belongs to blue-green light emission. |
