中文摘要：
将不同浓度的二[2-（4，三氟甲基-2-羟基苯基）]（Zn（4-TfmBTZ）2）掺杂到mcp层中制备了有机电致发光器件（OLED），器件的结构为IT0／NPB（40nm）／EZn（4-TfmBTZ）28％：mcp]（30nm）／Bphen（40nm）／LiF（1nm）／Al（200nm）。结果发现，Zn（4-TfmBTZ）2的掺杂浓度极大地影响器件的光谱和色度。在mcp层中，Zn（4-TfmBTZ）2质量分数为8％时，Zn（4-TfmBTz）2与电子传输层Bphen形成的激基复合物发射较强；但在掺杂浓度达到50％时，激基复合物的发射非常弱，几乎消失。由此通过mcp中Zn（4-TfmBTZ）2掺杂浓度的调节，实现了器件从蓝光色坐标为（0．22，0．27）到白光色坐标为（0．29，0．34）发射的调控。
英文摘要：
The doping devices with structure of ITO/NPB/mcp. Zn（4-TfmBTZ）z/Bphen/LiF/Al are fabricated,where the Zn（4-TfmBTZ）2 mass fraction in mcp layer is 8% and 50% ,respectively. The results show that the mass fraction of Zn（4-TfmBTZ）2 in mcp layer has important effect on the device performance,which contains spectrum and chromaticity. When the Zn（4-TfmBTZ）2 mass fraction is 8%, there exists a strong exeiplex emission of Zn（4-TfmBTZ） 2 and Bphen, while when the Zn（4-TfmB- TZ） 2 mass fraction is enhanced to 50 %, the exciplex emission almost disappears. The light color is tuned from blue light CIEx,y（0.22,0. 27）to white light CIEx,y （0.29,0. 34） at the same voltage by changing the Zn（4-TfmBTZ）2 doping amount in mop layer.
