| Popis: | We present a detailed design method of quantum dot-organic light emitting devices (QD-OLED) based on microcavity model. CdTe quantum dot is used as an emissive layer for blue, green and red emissions. We have simulated the internal photoluminescence emissions of the quantum dot layer by Gaussian function based on the published experimental results. Using these simulated internal photoluminescence emissions for different quantum dot sizes we have calculated the output emissions intensities of blue, green and red lights. We have investigated the effect of changing the device geometry on the emission intensity. We found that the emission intensity is highly depends on the device geometry. On the other hand, we found that the optimizations of the device structure are different for different emissions colors. |
