Abstract

In this study, an organic emission light diode (OLED) with the ability to adjust the color was created using two organic pigments as guests at the same time. Tunable color organic light-emitting diodes (OLEDs) using two dyes as guests have been fabricated and investigated. The structure of the manufactured part was ITO /PEDOT:PSS /PVK /C6:TPP:Alq3(x nm) /BCP/ Al. First, an organic norepinephrine diode blocker was made, and then the effect of different thicknesses of the Norgecil layer on the electrical characteristics, color, and optical coordinates of the diodes made was evaluated. The green diode was made at a thickness of 10 nm. By changing the thickness, an orange diode was obtained. It was found that by reducing the thickness, in addition to direct recombination, indirect recombination also has a significant effect on diode color. This made the color adjustable diode with thickness control. For part 2, the maximum brightness was obtained at 12 volts. Finally, the experimental results were compared with the simulated results.
