摘要：
Results of studying the optical and electrical characteristics of single- and two-layer polymer OLED structures with different thicknesses of radiating layers are presented. It is shown that the efficiency of the OLED structures with thick layers reaches 6.9 cd/A, while similar thin-layer structures have the efficiency 10 times smaller. An increase in the thickness of the radiating layer of the polymer as well as incorporation of additional electron transport layer leads to a decrease in the leakage current and an increase in the efficiency; however, it changes the electroluminescence spectrum of the device.
