Two-layer organic light-emitting diodes (OLEDs) in the range of 380 nm to 440 nm are reported. An efficient and stable electroluminescence with a maximum at 400nm was observed at room temperature under a forward bias about 5V. With the novel small molecular organic materials for blue to ultraviolet (UV) emission, the low operating voltage (5V) and high current efficiency (3 cd/A) have been obtained at 2mA/cm2.
