چکیده انگلیسی
The effect of host and interlayer structures on device performances of hybrid white organic light emitting diodes was studied by changing the energy level of host and interlayer materials. A mixed layer of hole transport type and electron transport type materials was used as a host and an interlayer. In the red:green/interlayer/blue stacked structure, a red shift of emission color was observed by increasing the highest occupied molecular orbital of the electron transport type material in the mixed layer. An optimization of the device structure gave a high current efficiency of 32.4Â cd/A with a color coordinate of (0.44, 0.45).
