In the latest issue of SpectroscopyNOW, I discuss how there are numerous redox-active compounds that emit light under electrical stimulation. Such materials are commonly organometallic complexes containing a transition metal and have been developed for labelling biomolecules for use in sensors. Related compounds are also being investigated for use in luminescent displays. Now, researchers in The Netherlands have used inkjet technology to “print” thin films of such materials to make new LED devices for display and backlighting applications.
This and more in the spectroscopy news round-up. A list of my news reports for the spectroscopy site can be found here.
