The advantages of using energy cluster evaporation (ECE) Alq3 deposition to fabricate organic light emitting devices (OLED) were discussed. The film surface morphology dose not change with evaporation techniques served by atomic force microscopy (AFM). It was found that OLEDs with thickness of 50nm, prepared by ECE showed better performance in both current-voltage and luminance-voltage curves than devices prepared by thermal evaporation. The results show that ECE prepared OLED with a smooth Al/Alq3 interface has superier electrical, luminance and electroluminescence (EL) efficiency.
