Organic light-emitting diodes (OLEDs) based on the double wide band gap emissive layers in the range of 380 nm to 440 nm are reported. An efficient electroluminescence with a maximum at 400nm was observed at room temperature under a forward bias about 10V. With the wide band gap organic materials for near-ultraviolet emission, the low operating voltage (5V) and high current efficiency (3 cd/A) have been obtained at 2mA/cm2.
