Electrically-Induced Light Emission in Polymer-Stabilized Proton Gradient Systems

Experiments with the chemically generated proton gradient, have lead to fabricate the system which emits the light, when electrically powered, owing to proton current flow. A polymeric scaffold preserves the stability of the system and, at the same time is playing a role of dopants of water, due to chemical character (acidic or basic) of side groups, which are responsible for gradient formation. The

results of experiments with the chemical model of the proton gradient, the protonic p-n junction, as a light emitting diode, make a “proof of concept”, which opens the way into new light generating process and new device (protonic LED), but also, to general understanding the proton gradient role in

the light emission processes.
