摘要：

The article initially discussed the method of preparing Alq3 coated by SiO2 to improve the material interface of organic light emitting device(OLED), which can prolong the lifetime of OLED. Transmission electron microscope(TEM), photoluminescence spectra(PL), thermo gravimetric analysis(TG) were used to characterize superficial morphology, luminescence and thermal stability properties of products, respectively, while the film microstructure of products was analyzed with scanning electron microscope(SEM) and X-ray photoelectron spectrometer(XPS). Finally, OLEDs with two-layer structure were fabricated with Alq3 and Alq3 coated by SiO2 as emitting layer, respectively, and their electroluminescent properties were tested. Results showed that this method introduced in this article can greatly improve the lifetime of OLED.
