Software Design And Realization Of Organic Light-emitting Devices Based On Aggregation-induced Emission

Organic light-emitting devices (OLEDs),with the advantages of simple structure,flexibility, self-emission and quick response, have attracted researchers’ interests allover the world, especially in recent years for flat panel display and solid state lightingsource. Meanwhile, the simulation platform of OLED gets a rapid development on thisground, but the simulation platform for aggregation-induced emission OLED is stillrare.Therefore, in this work, taking self aggregation-induced emissionfactor ofA(x) andquenching factor of β(x) into consideration, and we optimized the simulation platformof aggregation-induced emission OLEDs from design theory to structure configurationusingthe aggregation-induced emission material series of TF as an example. With thestart of obtaining intrinsic index of material, we focused on analog research of opticalcharacteristics of material and bring emissionfactorof A(x) and quenching factor of β(x)to materials. As a result, we obtained the ideal structure to improve software simulationand verified its reliability and accuracy according to that the characterizations of thefabricated OLED devices. The main content of this Master Degress thesis are listed asfollows:1. According to the analysis of mechanism of OLED devices, we obtainedthealgorithm and design of convetional OLEDs simulation tool as well as the excitonsquenching effectmechanism of aggregation-induced emission material by introducingaself aggregation-induced emissionfactorof A(x) and a quenching factor of β(x) to workout corresponding program and configuration.2. Withthe aggregation-induced emission material series of TF, includingTF-1,TF-2and TF-3, we tried to obtain their intrinsic parameter by UV-visible absorptionspectra, aggregation-induced emission and photoluminescence (PL) spectra. Then, wegot the fundamental data that simulation software for better supporting analogsimulation of devices in the later period.3. The flow chart of necessity was design, and program design diagram in term ofdifferent simulation function was completed. The OLEDs based on the TF materialswere fabricated and optimized. Based on theconventional OLED simulation platform, the self aggregation-induced emissionfactorof A(x) and quenching factor of (x)wereadded to improve the whole analog simulation configuration of devices, and a morematching analog simulation platform was accomplished.4. The normal aggregation-induced emission OLED devices were fabricated, andtheir performances were characterized. Then, the error of aggregation-induced emissionOLED simulation platform was tested. The electroluminescence (EL) spectra showedthat,the EL spectra peaks of TF-1, TF-2and TF-3were located at419nm,430nm and439nm at a bias voltage of5V, respectively, exhibiting a blue color light emission. Thefinal data clearly proved thatthe OLED simulation platform for self aggregation-inducedelectroluminescence in this work is very effective.The results showedthat, by introducing a self aggregation-induced emissionfactorofA(x) and a quenching factor of β(x), and investigating the characteristics of OLEDconsisting of aggregation-induced emission material series of TF, the selfaggregation-induced emission OLED simulation platform constructed in this work isvery reliable and accurate. This work paved the way for construction of more reliableand more accurate simulation platform for self aggregation-induced emission OLED.
