I’ll explain how it’s done, just in case you have some old ruthenium tris-bipyridine lying around, and want to try out your new electrospinning machine. (Yeah, the one in your garage that your wife yelled at you for buying on Ebay last summer. You’ll show her!) Cornell University researchers researchers spun the fibers from a mixture of the metal complex ruthenium tris-bipyridine and polymer polyethylene oxide using a technique called electrospinning.
They found the fibers emitted orange light when excited by low voltage through micro-patterned electrodes- just like a tiny light bulb. Which means that this collaboration of experts in organic materials and nanofabrication, have developed the smallest organic light-emitting device ever created.
The scientists hope such a localized light source will be useful in sensing, microscopy, flat-panel displays and that other applications will eventually be discovered as well.
This research can be found in the journal Nano Letters. Posted by Rebecca Sato.
