The Effect of Electrode Materials on the Optical Characteristics of Infrared Quantum Dot-Light Emitting Devices

Progress In Electromagnetics Research C, Vol. 19, 47-59, 2011
Abstract
We present an optical model based on Green function to investigate the effect of using Single Wall Carbon Nanotube (SWCNT) as anode for infrared light emitting devices (IR QD-LEDs). To the best of our knowledge there is no report in using SWCNT as anode in IR QD-LEDs. We have studied the emitted power distribution among the different optical modes (air, substrate, anode/organics, and surface plasmon modes (SP)), angular intensity distribution, and the emission spectral characteristics. We have found that the light outcoupling efficiency of IR QD-LEDs based on SWCNT as anode was increased nearly by a factor of 4 relative to that one based on indium-tin oxide (ITO). We also investigated the effect of using different cathode materials on the optical characteristics of IR QD-LEDs.
