Enhanced efficiency of organic light emitting diodes by NaOH surface treatment of indium tin oxide anode

LED organici con emissione nel blu

We report the development of blue organic light emitting diodes (OLEDs) based on molecular materials. Electrical characteristics and quantum efficiency of single layer devices and triple layer devices comprising further a hole blocking layer and an electron injection layer are compared and prospects for applications to passive matrix displays and fluorescence integrated biosensors are also discussed.
