The hybrid quantum dot (QD) electroluminescent devices are fabricated by mixing every two kinds of QDs in the red, green, blue three types of QDs in a ratio 1:1, which are based on the structure of ITO/PEDOT:PSS/QDs/Al. In the systematical investigation of the electroluminescent spectrum, when the voltage increases, we find that the luminance intensity of the controlling devices continues to grow, while the hybrid QD devices first increase then decrease, showing that there is an energy transfer in the hybrid QD devices. And we also obtain the relationships among the energy transfer efficiency, the critical energy transfer distance, the donor-acceptor distance, and the electric field.
