摘要：
Single photon-emission in organic LEDs (OLEDs) has been evaluated. The device structure of ITO/MoO3 (20 nm)/alpha-NPD (50 nm)/Alq3 (50 nm)/LiF (1 nm)/Al (70 nm) was evaporated on an ITO substrate. In addition to the common OLED measurements, photon-counting measurements were carried out, where, the light is extracted through a diameter of 100 mu m phi pinhole, and the voltage was precisely controlled within 5 mV steps using a power supply. By decreasing the voltage below 2.25 V, an average photon counting of "1" was observed at 2.135 V.
