Alternative current electroluminescence and flexible light emitting devices
Electroluminescence (EL), the light emission under an applied electrical potential, is one of several key light emitting techniques applied over a vast range of applications. Alternative Current Electroluminescent (ACEL) is one of the major light emitting techniques discussed under EL. Even though it possesses some intrinsic advantages over Light Emitting Diodes (LEDs) and Light Emitting Cells (LEC), it has not been thoroughly discussed like LEDs and most of the time has been kept under the shadow of LEDs. On the other hand, flexible light emitting devices have become an emerging trend in the field as they are widely applied in consumer electronics and wearable devices, where an ACEL technique can make a significant impact for their development. This review discusses the ACEL technique in detail covering different device architectures, materials and fabrication methods highlighting the use of electrospinning techniques. In the second part, the review briefly summarizes research works in the flexible light emitting field, covering both optical and mechanical performances.
