The p-n junction formation


This short video shows the p-n junction formation preceeding light emission in a light-emitting electrochemical cell. Play by clicking the image to the right.

Colors of light

Multicolored LECs

Light-emitting  electrochemical cells can be designed to emit all different colors. This can be seen in this photograph, showing devices fabricated in our lab. Click the image to view it in full size.

White light

White light is desired for indoor lighting. The photograph to the right demonstrates a white light device. Enlarge the picture by clicking on it.


Flexible devices

Flexibility is one of the intriguing features of the LEC technology. The device to the right shows light emission from a device under bending.
