Abstract

In this paper, a highly efficient charge generation layer (CGL)-based blue organic light-emitting diode is proposed. The proposed device contains a CGL composed of two materials, 1,1-bis[(di-4-tolyamino)phenyl]cyclohexane (TAPC) and 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN), which act as hole and electron injectors, respectively. The CGL in the proposed device is placed outside the emissive layer, which provides better luminescence and current as compared with four other CGL-based devices D2, D3, D4 and D5 where CGL is utilized below the cathode, above the anode, near both electrodes (cathode and anode) and inside the emissive layer, respectively. The proposed device exhibits noteworthy results, achieving peak current and luminescence values of 0.44 A and 3636.3 cd/m2, respectively. The luminescence obtained is improved by about 16.8, 2.3, 1.7, 3, and 1.6 times compared with D1, D2, D3, D4 and D5. Thickness optimization of the proposed device is also outlined. The optimized device shows maximum luminescence of 4670 cd/m2.
