OLEDs for lighting: state of the art and ENEA competence
Paolo TASSINI (ENEA)
OLEDs (Organic Light Emitting Diodes) are one of the most important commercial successes of the organic electronics. These devices are under study and development now for decades, for lighting and display applications. From micro-displays to huge TV sets to design luminaires and to interior lamps, OLEDs are unfolding their peculiar properties, like large active area, flexibility, lightness, thinness, efficiency, colour tunability, possibility to be also fabricated using innovative roll-to-roll processes, which have attracted the attention and the dedication of many companies and research institutions [1][2][3].
ENEA Laboratory of Nanomaterials and Devices (SSPT-PROMAS-NANO) in Portici Research Centre has been working on OLEDs, and on organic electronics in general, for more than ten years. Activities are dedicated to increase the emitting area and the light output, to improve the devices efficiency, to study and prevent the degradation phenomena and increase the devices life-time, to study new electroluminescent materials, and to develop innovative fabrication processes.
