Three layers of moldable light-emitting polymer blended with a small amount of carbon nanotubes glow when an alternating current is passed through them.
[1][2][3] As cited from the Carroll Research Group at Wake Forest University, "To date our brightest device – without output couplers – exceeds 18,000 cd/m2."
Instead, the light emitting component is a layer of polymer containing an iridium compound which is doped with multi-wall carbon nanotubes.
This planar light emitting structure is energized by an AC field from insulated electrodes.
[6] The technology was developed by a team headed by Dr. David Carroll of Wake Forest University in Winston-Salem, North Carolina.
