　　In this thesis, we focused on how to fabricate a simple-structure bilayer ultraviolet organic light emitting diode (UV-OLED). Furthermore, the UV-OLEDs were applied as white light source by color conversion materials. Consequently, a white organic light emitting diode was .
　　In the first part of this search, CBP and TPBi thin films were deposited with different thickness to investigate the characteristics of the UV-OLED. At the second part, an anode buffer layer was also deposited to investigate the effect on the characteristics of the devices. Furthermore, the admittance spectroscopy proved useful in interface modification because of anode buffer layer. In the last part, we discussed the applications of UV-OLED.
　　In this study, we report on the red-shift of UV-OLED with various CBP and TPBi thickness by micro-cavity effects. In addition, the device with broadband EL spectrum at high voltages has been demonstrated because of eletroplex effect in the interface between CBP and TPBi layers. In the anode buffer layer study, the series resistance of UV-OLED with anode buffer has been reduced by admittance spectroscopy investigations.
