The mechanism of efficiency enhancement with proper thickness of DPVBi layer for blue organic light-emitting devices (BOLED)
چکیده انگلیسی

We report on the fabrication of blue organic light-emitting devices (BOLEDs) with structure: ITO/NPB/DPVBi/Alq3/LiF/Al. The hole-blocking effect in NPB/DPVBi interface was indirectly demonstrated and deduced by inserting DCJTB layer. In addition, the effect of the device with better J–V characteristics because of the extra DCJTB layer is discussed as well. However, the performance of devices was investigated with various thicknesses of DPVBi layer. The result shows that the device with proper thickness of DPVBi layer generating better electron injection enhances efficiency and luminance for BOLED.
